A nurse is preparing to test cranial nerve I. Which item does the nurse obtain to test this nerve?

Correct Answer: C

Rationale: To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint. Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I. Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve). Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

Correct Answer: D

Rationale: The correct answer is cranial nerve XII (hypoglossal nerve). When testing cranial nerve XII, the healthcare provider inspects the symmetry and movement of the tongue. The tongue should protrude in the midline when the client sticks it out. Cranial nerve IX (glossopharyngeal nerve) and X (vagus nerve) are tested by depressing the tongue with a blade to observe pharyngeal movement and gag reflex. Cranial nerve V (trigeminal nerve) is responsible for testing the muscles of mastication, not tongue protrusion.

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.
