Correct Answer: D

Rationale: The nurse should follow up on the client's lack of a support system. Even if there is no family in the area, there are supportive resources in the community that may help the client through the pregnancy and into motherhood. It is normal for the client to worry about labor, address financial concerns, and express displeasure from early pregnancy symptoms such as nausea. However, the priority is to address the client's statement about preparing to handle the pregnancy on her own due to the absence of nearby family support. This could have significant implications for the client's emotional well-being and ability to cope effectively throughout the pregnancy journey.

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: B

Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.

Correct Answer: D

Rationale: When assessing for costovertebral angle tenderness, sharp pain on percussion of the area indicates inflammation of the kidney or paranephric area. The correct technique involves placing one hand over the 12th rib, at the costovertebral angle, and thumping that hand with the ulnar edge of the other fist. The client normally feels a thud and should not experience pain. Ovarian infection, liver enlargement, or spleen enlargement are not associated with the costovertebral angle tenderness. Therefore, the correct answer is kidney inflammation.

Correct Answer: D

Rationale: The correct placement for auscultating the apical heart rate in the area of the mitral valve is the fifth left interspace at the midclavicular line. Placing the stethoscope in the second left interspace would be to listen to the pulmonic valve, the second right interspace is for the aortic valve, and the left lower sternal border is for the tricuspid valve.
