A student nurse has been assigned to teach fourth graders about hygiene. While preparing, the student nurse adds information about the sweat glands. Which of the following should be included while discussing this topic?
- There are two types of sweat glands: the eccrine and the sebaceous.
- The evaporation of sweat, a dilute saline solution, increases body temperature.
- Eccrine glands produce sweat and are mainly located in the axillae, anogenital area, and navel.
- Newborn infants do not sweat and use compensatory mechanisms to control body temperature.

temperature regulation
Functions of the skin include protection, prevention of penetration, perception (of touch, pain, temperature, and pressure), temperature regulation, identification, communication, wound repair, absorption and excretion, and production of vitamin D.
The skin produces vitamin D, not vitamin C.
The basal cell layer of the epidermis forms new skin cells. Melanocytes produce melanin, which gives brown tones to the skin and hair.
Sebum is produced by the sebaceous glands to lubricate the skin and hair.
Risk factors that may lead to skin disease and breakdown include:
- loss of protective cushioning of the dermal skin layer.
- decreased vascular fragility.

Which of the following tests provides a precise quantitative measure of hearing?
- Tuning fork tests
- Romberg test
- Audiometer test
- Whispered voice test
Audiometer test
An audiometer gives a precise quantitative measure of hearing by assessing the person’s ability to hear sounds of varying frequency.
The tuning fork tests (Weber and Rinne) are inaccurate and should not be used for general screening. The Romberg test assesses the ability of the vestibular apparatus in the inner ear to help maintain standing balance . The whispered voice test is nonquantitative; this test documents the presence of hearing loss but does not measure the degree of loss.
The labyrinth of the inner ear is responsible for maintaining the body’s:
- binaural interaction.
- air conduction
- equilibrium
- pressure equalization
equilibrium
The labyrinth maintains the body’s equilibrium.
Binaural interaction is controlled by the brainstem and permits locating the direction of a sound. The normal pathway of hearing is by air conduction. The eustachian tube allows equalization of air pressure on each side of the tympanic membrane.

Down syndrome.
Macroglossia occurs with Down syndrome; it also occurs with cretinism, myxedema, and acromegaly. A transient swelling also occurs with local infections.
In addition to initiating digestion of food, saliva also:
- augments taste sensation.
- protects the mucosa from caustic substances.
- inhibits overgrowth of bacteria in the mouth.
- cleans and protects the mucosa.
cleans and protects the mucosa.
Saliva moistens and lubricates the food bolus, starts digestion, and cleans and protects the mucosa.
One of the purposes of the paranasal sinuses is to:
- lighten the weight of the skull bones.
- warm and moisten the inspired air.
- amplify sound.
- augment the sensory sensation of smell.
lighten the weight of the skull bones.
The paranasal sinuses lighten the weight of the skull bones.
Nasal mucosa and nasal turbinates warm, humidify, and filter the inhaled air.. The paranasal sinuses serve as resonators for sound production. Olfactory receptors (responsible for the sensation of smell) are located in the nasal cavity and septum and merge into the olfactory nerve.
The parotid gland’s duct that opens into the mouth opposite the second molar is:
- the Wharton duct.
- the salivary duct.
- Stensen duct.
- the sublingual duct.
Stensen duct.
The parotid gland’s duct is the Stensen duct; it runs forward to open on the buccal mucosa opposite the second molar.
The Wharton duct (for the submandibular gland) runs up and forward to the floor of the mouth and opens at either side of the frenulum.
The mouth contains three pairs of salivary glands, which are the parotid gland, the submandibular gland, and the sublingual gland.
The sublingual gland lies within the floor of the mouth under the tongue.

cyanosis
Increased tactile fremitus would be evident in an individual who has which of the following conditions?
- Emphysema
- Pneumonia
- Crepitus
- Pneumothorax
Pneumonia
Fremitus is a palpable vibration. Increased fremitus occurs with compression or consolidation of lung tissue (e.g., lobar pneumonia).
Decreased fremitus occurs when anything obstructs transmission of vibrations (e.g., obstructed bronchus, pleural effusion or thickening, pneumothorax, or emphysema).
Crepitus is a coarse crackling sensation palpable over the skin surface. It occurs in subcutaneous emphysema when air escapes from the lung and enters the subcutaneous tissue.
____ is an absence of red-pink tones from the oxygenated hemoglobin in blood
pallor
A clinical manifestation common in an individual with chronic obstructive pulmonary disease (COPD) is:
- periodic breathing patterns.
- pursed-lip breathing.
- unequal chest expansion.
- hyperventilation.
pursed-lip breathing.
An individual with COPD may purse the lips in a whistling position. By exhaling slowly and against a narrow opening, the pressure in the bronchial tree remains positive, and fewer airways collapse.
Periodic breathing patterns are Cheyne-Stokes or Biot respirations. Cheyne-Stokes respirations occur in heart failure, renal failure, meningitis, drug overdose, and increased intracranial pressure; this type also normally occurs in infants and aging persons during sleep. Biot respirations occur with head trauma, brain abscess, heat stroke, spinal meningitis, and encephalitis.
Unequal chest expansion occurs when part of the lung is obstructed or collapsed, as with pneumonia, or when guarding to avoid postoperative incisional pain or pleurisy pain.
Hyperventilation is a normal response to fever, fear, or exercise; respiration rate also increases with respiratory insufficiency, pneumonia, alkalosis, pleurisy, and lesions in the pons.

A normal finding from voice sounds is egophony; “eeeee” heard through the stethoscope clearly.
A normal finding from voice sounds is bronchophony; normal voice transmission is soft, muffled, and indistinct. A normal finding from voice sounds is whispered pectoriloquy: whispered sound is faint, muffled, and almost inaudible.
_____ is an increase in bilirubin in the blood causing a yellow color in the skin
jaundice
The gradual loss of intraalveolar septa and a decreased number of alveoli in the lungs of the elderly cause:
- hyperventilation.
- spontaneous atelectasis.
- decreased surface area for gas exchange.
- decreased dead space.
decreased surface area for gas exchange.
The histologic changes result in less surface area for gas exchange.
The function of the trachea and bronchi is to:
- transport gases between the environment and the lung parenchyma.
- condense inspired air for better gas exchange.
- moisturize air for optimum respiration.
- increase air turbulence and velocity for maximum gas transport.
transport gases between the environment and the lung parenchyma.
The trachea and bronchi transport gases between the environment and the lung parenchyma.
____ tiny, punctate red macules and papules ion the cheeks, trunk, chest, back, and buttocks
erythema toxicum
Stridor is a high-pitched, inspiratory crowing sound commonly associated with:
- upper airway obstruction.
- atelectasis.
- congestive heart failure.
- pneumothorax.
upper airway obstruction.
Stridor is associated with upper airway obstruction from swollen, inflamed tissues or a lodged foreign body.
Percussion of the chest is:
- a useful technique for identifying small lesions in lung tissue.
- helpful only in identifying surface alterations of lung tissue.
- is not influenced by the overlying chest muscle and fat tissue.
- normal if a dull note is elicited.
helpful only in identifying surface alterations of lung tissue.
Percussion detects only the outer 5 to 7 cm of tissue; it will not penetrate to reveal any change in density deeper than that.
An abnormal finding must be 2 to 3 cm wide to yield an abnormal percussion note. Percussion findings (resonant notes) may be modified by a muscular chest wall of an athlete or subcutaneous tissue of the obese person. Resonance is a low-pitched, clear, hollow sound that predominates with percussion of healthy lung tissue.
Which of the following correctly expresses the relationship to the lobes of the lungs and their anatomic position?
- Upper lobes—lateral chest
- Upper lobes—posterior chest
- Lower lobes—posterior chest
- Lower lobes—anterior chest
Lower lobes—posterior chest
The posterior chest is almost all lower lobe. The anterior chest contains mostly upper and middle lobe with very little lower lobe.
An increase in the transverse diameter of the chest cage in a pregnant female is due to a(n):
- compensatory increase in respiratory parenchyma.
- increase in estrogen.
- increase in surfactant.
- increase in tidal volume.
increase in estrogen.
The increase in estrogen level during pregnancy relaxes the chest cage ligaments. This allows an increase in the transverse diameter of the chest cage by 2 cm, and the costal angle widens.

acrocyanosis
_____ large round or oval patch of light
brown usually present at birth
cafe au lait
_____ yellowing of skin, sclera, and mucous membranes due to increase numbers of red blood cells hemolyzed following birth
physiologic jaundice
