During the examination of a client's throat, a nurse touches the posterior wall with a tongue blade and elicits the gag reflex. The nurse documents normal function of which cranial nerves?

Correct Answer: D

Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.

Correct Answer: D

Rationale: To best listen to breath sounds, the nurse should have the client sit, leaning slightly forward, with arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little deeper than usual, but to stop if feeling dizzy. The nurse should hold the flat diaphragm end piece of the stethoscope firmly against the client's chest wall. It is crucial to listen for at least one full respiration in each location on the chest to assess breath sounds accurately. Side-to-side comparison is essential in breath sound assessment. Therefore, options A, B, and C are incorrect as they do not align with the correct procedure for listening to breath sounds.

Correct Answer: C

Rationale: The nurse is documenting an abnormal bronchophony assessment finding. Bronchophony is a technique where the nurse asks the client to repeat a specific word, such as 'ninety-nine,' while listening through the stethoscope. Normally, the voice transmission is soft, muffled, and indistinct. However, if there is a pathologic condition increasing lung density, the nurse will hear the word clearly, indicating an abnormality. Vesicular breath sounds are normal sounds heard over peripheral lung fields and are not related to vocal resonance assessment. Egophony involves the client phonating a long 'ee-ee-ee-ee' sound, not repeating a specific word. Whispered pectoriloquy involves whispering a phrase like 'one-two-three,' not repeating a specific word. In these cases, normal findings are 'eeeeee' for egophony and a muffled, almost inaudible sound for whispered pectoriloquy.

Correct Answer: D

Rationale: Chloasma, also known as the mask of pregnancy, is described as tan-to-brown patches on the face. This hyperpigmentation results from hormonal changes during pregnancy. Vitiligo is characterized by depigmented patches, erythema is redness of the skin due to increased blood flow, and cyanosis is a bluish discoloration due to poor circulation or lack of oxygen, none of which are typical skin-color variations during pregnancy. Therefore, in a pregnant client, the most likely normal skin-color variation to be displayed is chloasma.

Correct Answer: B

Rationale: Single mothers with two or three children are indeed the fastest-growing segment of the homeless population. These families, where the majority of children are under the age of five, make up more than one-third of the homeless population in the United States. While single, adult men have traditionally been the largest group in the homeless population, single mothers with children have been increasing in numbers. Runaway adolescents, although a significant group of homeless children, do not represent the fastest-growing segment of the homeless population. Single, adult women are not specified as the fastest-growing segment.
