Practice Questions r/t Endocrine Concerns Flashcards
An emaciated client is to receive NPH insulin 20 units 1 hour before breakfast daily. The insulin should be administered:
- intramuscularly at 90 degrees
- subcutaneously at 90 degrees
- intramuscularly at 45 degrees
- subcutaneously at 45 degrees
Emaciated clients should have insulin administered at a 45-degree angle into subcutaneous tissue. The first factor to consider is the emaciated state of the client - this question assumes that this means there is a need to choose a 45 over 90 degree angle as using a 90-degree angle could cause the needle to go through the subcutaneous tissue into an emaciated client
you don’t give insulin IM
an adolescent 15 years of age is hospitalized with type 1 insulin-dependent diabetes. Which of the following is essential to teach the client?
- insulin dosage will be determined by food intake
- insulin will have to be administered for the rest of the client’s life
- insulin dosage will be adjusted by the way the client eats
- insulin will be adjusted as the client grows older
exogenous insulin will be needed to be administered for the rest of the client’s life as persons with T1 have no endogenous insulin
Food intake, eating habits, and growth patterns are important factors in appropriate insulin dosing. However, the most essential to know is insulin will be required from now on
The only insulin that can be administered IV is: _________________
Regular Insulin (aka rapid-acting aka Humulin R)
It is clear and does not contain modifying agents (also it makes sense in that Regular insulins effect happens at pace that can be adjusted using IV admin - something like a long-acting/prandial would be given and effects not seen until way later - totally risky)
you client is receiving 30 units of NPH insulin daily at 07:00. What would the client need to do each day?
- exercise for 30 minutes prior to lunch
- consume a snack each day at 16:00
- exercise for 30 minutes prior to bedtime
- consume a bedtime snack at 21:00
NPH insulin peaks between 6 and 8 hours after administration. A snack should be consumed at 1600 to prevent hypoglycemia.
(onset - 2 hours, peak - 6-8, duration 12-16)
daily exercise should be accounted for and adjustments in daily insulin dosages may be needed. Additional glucose needs to be consume when client exercise more than usual as exercise has a hypoglycemic effect
long-acting insulin given at bedtime requires a bedtime snack the next day (onset 2 hours, peak 16-20, duration 24+ hours)
A 26-year-old gravida 1 has type 1 insulin-dependent diabetes. Due to a change in insulin requirements during the first trimester, the nurse will carefully observe the client for signs of:
- hypoglycemia
- ketoacidosis
- hyperglycemia
- pregnancy-induced hypertension
The nurse will observe client for signs of hypoglycemia. There is a decreased need for insulin in the first trimester. the level of human placental lactogen (HPL) (an insulin antagonist) is low. Also, the client and developing fetus use more glucose and glycogen
ketoacidosis accompanies hyperglycemia, not hypoglycemia
pregnancy-induced hypertension is not a factor in first trimester (personal aside, based on my course notes, hypertension noted in first trimester is typically considered to have been pre-existing or related to other causes)
a client is to receive 12 units of Regular insulin and 26 units of NPH insulin subcutaneously daily. Which procedure is correct.
- Store all insulin in the refrigerator
- massage the injection site after the injection
- draw up the NPH insulin first, then the Regular
- Roll the NPH insulin bottle between the pals of the hands prior to drawing it up
NPH insulin is an intermediate-acting insulin and should be rolled between the palms of the hands to thoroughly mix the dose prior to withdrawal from vial
insulin may be left at room temperature for up to 4 weeks unless the room temperature is higher than 85 F or below freezing. Extra insulin may/should be stored in fridge
after injecting insulin, some pressure should be applied as needle is being withdrawn. The swab should be held in place a few second, but not massaged.
when mixing intermediate-acting with Regular, Regular should always be drawn up first (RN - R before N)
your client was started on 0.1 mg of Synthroid daily. What teaching will the client need in relation to this medication?
- take the medication with meals
- do not substitute generic brands
- dosage can be self-adjusted based on energy needs
- expect to loose 10 to 15 pounds within the first 6 months of therapy
Clients receiving Synthroid (levothyroxine) should not substitute generic brands as different brands have different preparations and may no be the same. To maintain appropriate thyroid levels, substitutions should not be made.
does not need to be taken with meals. Should be taken at same time each day to establish consistency
dose should not be self-adjusted as it should be done based on serum laboratory values and only done under direction of a qualified health care provider
weight loss may occur as result of increased basal metabolic rate, but not for all clients!
your client had a bilateral adrenalectomy and Solu-Cortef has been prescribed. You know the purpose of this medication is to:
- lower serum glucose
- relieve postoperative pain
- prevent adrenal insufficiency
- decrease risk of postoperative stress ulcers
Hydrocortisone (Solu-Cortef) will replace the corticosteroid normally produced in the adrenal gland’s cortex and prevent adrenal insufficiency.
tends to raid, not lower serum glucose levels
not an analgesic and will not relieve postop pain
causes gastric irritation and should be given with meals (does not decrease risk of postop stress ulcers)
a 22-year-old female is admitted to the unit with a BGM of 822 mg/dl and an arterial blood pH of 7.02. The client is unresponsive. The insulin type and rout you anticipate administering is:
- humulin N given IV
- humulin R given IV
- humulin 70/30 given IV
- Humulin N given subcutaneously only
Humulin R is rapid-acting insulin and can be administered IV to treat high blood glucose levels.
Humulin N is a suspension and cannot be given IV
Humulin 70/30 is a mix of intermediate and regular, it cannot be given IV
Rapid-acting is needed as pt is unresponsive. Humulin N is too slow via subcutaneous route and cannot be given via IV route
A client is admitted to the nursing unit with a medical diagnosis of chronic hypothyroidism. The nursing assessment reveals a body temperature of 90 F, and apical heart rate of 58, and a respiratory rate of 10 breaths per minute. The nurse immediately recognizes these findings as indicative of:
- hypercalcemia
- hypermagnesemia
- metabolic acidosis
- myxedema coma
The nurse will associate the client’s symptoms with myxedema coma. A body temperature of 90 F, an apical of 50 BPM, and respirations of 10 per minute are classic symptoms of myxedema coma seen in clients with hypothyroidism
hypercalcemia (calcium serum levels above 10.1 mg/dl) may be seen in hyperthyroidism, not hypothyroidism
hypermagnesemia (magnesium serum levels above 2.1 mg/dl) is associated with acute adrenocortical insufficiency and untreated diabetic ketoacidosis
symptoms of metabolic acidosis include increased respiration rate and depth, not bradypnea
A client with diabetes has been taking tolazamide 100 mg po daily. The client has just had a hip replacement and is to be on Coumadin 5 mg PO daily. You anticipate the following potential changes:
- an increase in serum glucose levels
- a decrease in prothrombin times
- a decrease in serum glucose and an increase in prothrombin times
- an increase in serum glucose and an increase in prothrombin times
You anticipate a decrease in serum glucose and an increase in prothrombin times. Tolazamide (Tolinase) and Warfarin (Coumadin) tend to augment each other’s actions. therefore, the prothrombin time will increase and the serum glucose levels will be lowered even more, since the two drugs are being used in combonation
A client arrives in the ED restless, hypotensive, confused, and vomiting. The client’s friend states the client stopped taking betamethasone 4 days ago because it tended to cause heartburn. You anticipate administration of:
- large doses of loop diuretic
- narcotic
- sodium bicarbonate and Humulin N intravenously
- glucocorticoids
you will anticipate administration of glucocorticoid. This person is exhibiting classic signs of adrenal insufficiency, probably due to the abrupt cessation of glucocorticoid therapy
diuretics are usually not given to hypotensive clients because they lower BP by decreasing circulation volume
an analgesic is not anticipated since there is no indication client is experiencing pain
there is no indication that patient is experiencing something like metabolic acidosis that would require sodium bicarbonate
your client is being treated with glucocorticoids for adrenal insufficiency secondary to abrupt withdrawal of cortisone. Your client’s family member inquires about what happened to the client’s adrenal glands. You explain:
- the adrenal glands were destroyed by the cortisone therapy
- the adrenal glands were not really affected and “adrenal insufficiency” is just a loosely applied term
- the adrenal glands have probably developed tumors
- the adrenal function was suppressed during cortisone therapy
You will explain that the function of the adrenal glands is suppressed during glucocorticoid therapy and abrupt cessation of glucocorticoids does not allow time for the adrenal glands to resume normal functioning
there is no evidence of permanent adrenal damage
the adrenal function was affected by glucocorticoid use
there is no evidence of a tumor
Your client has been placed on a regime of methylprednisolone because of severe allergies. Your client teaching will include instruction to:
- taper the medication dose according to the regime
- take the medication only on days when allergies flare up
- discontinue taking the medication when symptoms of allergies are no longer noticeable
- contact the physician because this is not a recommended therapy for allergic reactions
The client will be taught to taper the methylprednisolone (Medrol) according to the regime. Tapering the dosage will avoid adrenal insufficiency
corticosteroids like methyprednisolon are to be taken on a regular basis - not just when an allergy is bothersome
sudden withdrawal can precipitate adrenal insufficiency
this is an appropriate med for treatment of allergic reactions
During a thyroidectomy, a client’s parathyroid glands were inadvertently removed. Which of the following laboratory tests must be monitored very closely?
- urine specific gravity
- creatine kinase-MB isoenzyme
- serum calcium
- amylase
Serum calcium should be monitored carefully. The parathyroid gland’s function is to increase calcium absorption and increase blood calcium levels. Serum calcium levels must be scrupulously monitored. Extreme disturbances in calcium levels may lead to tetany or lethal arrhythmias
PTH (parathyroidhormone) does not directly affect urine specific gravity.
CK and CK-MB are used to confirm acute MI in hours following event - not related to PTH
The nurse recognizes that clients receiving large dosages of vasopressin (ADH) may experience:
- facial pallor
- headache
- flushing
- dyspnea
Vasopressin (Pitressin) causes vasoconstriction, this can result in facial pallor
clients may experience dizziness and a pounding sensation in the head, but not a headache
clients may experience perspiration, paleness, and perioral blanching, but not flushing (opposite)
dyspnea is not associated with admin of Pitressin
An adolescent with diabetes asks about the use of alcohol. The most appropriate counsel would be:
- diabetics require more insulin when they consume alcohol
- alcohol consumption increases blood glucose
- hypoglycemia occurs with alcohol consumption
- diabetics who consume alcohol become intoxicated easily
Diabetics should be taught that alcohol consumption inhibits release of glycogen from the liver, which results in hypoglycemia
alcohol doesn’t increase blood glucose or need for insulin
diabetes does not change when an individual becomes intoxicated - however, diabetics may develop hypoglycemia that goes unrecognized because of the similarity between symptoms and those symptoms associated with alcohol intoxication
The physician prescribed 20 units of isophane (NPH) insulin 30 minutes before breakfast daily for a client with diabetes mellitus. The client is to have a midafternoon snack of milk and crackers. The client asks the nurse why the snack is necessary. Which response by the nurse would be bes?
- it will improve your nutritional status
- it will improve carbohydrate metabolism
- it prevents an insulin reaction
- it prevents diabetic ketoacidosis
it prevents hypoglycemia at peak action of isophaone insulin, which occurs 6 to 12 hours after administration.
A client with hypoparathyroidism complains of tingling of the lips, hands, and face. You notify the physician because you suspect the development of which complication?
- syndrome of inappropriate antidiuretic hormone
- tetany
- myxedema
- Cushing’s syndrome
The nurse will suspect the development of tetany. Hypoparathyroidism causes a decrease in serum calcium levels due to lack of PTH. A decrease in calcium ion concentration causes tetany. Signs of tetany syndrome include tingling lips, hands, and feet; muscle tension, stiffness, and paresthesia (sensation of numbness)
SIADH is a complication of conditions such as increased intracranial pressure or endocrine and pulmonary disorders. It is associated with an increase in secretion of ADH which causes extracellular volume overload and a decrease in urine output
Myxedema is a type of hypothyroidism associated with extreme symptoms of hypothyroidism
Cushing’s syndrome results from excessive adrenocortical activity, not hypoparathyroidism
hyperthyroidism is suspected in a 28-year-old client. Prescriptions include a radioactive iodine uptake test. The nurse will explain to the client that the chief purpose of a radioactive iodine uptake test is to:
- ascertain the ability of the thyroid gland to produce thyroxine
- measure the activity of the thyroid gland
- estimate the concentration of thyrotropic hormone in the thyroid gland
- determine the best method of treating the thyroid condition
The purpose of radioactive iodine uptake test is to measure the activity of the thyroid gland. The thyroid gland cannot distinguish between regular iodine and radioactive iodine. By administering tracer doses, the percentage of radioactive iodine used by the gland to produce thyroxine provides and indicator of gland activity. In clients with hyperthyroidism, the gland may use up to twice as much iodine as a euthyroid (normal) state
the test does not: determine the ability of the thyroid to produce thyroxine, estimate the concentration of thyrotropic hormone (thyroid-stimulating hormone)
treatment will not be addressed until assessment has been completed. This test is only one consideration!
