Adult Health 2 Final Exam

1. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?

Correct answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

2. The unlicensed assistive personnel (UAP) reports to the nurse that a client refused to bathe for the third consecutive day. What action is best for the nurse to take?

Correct answer: A

Rationale: The correct action for the nurse to take is to ask the client why the bath was refused. Understanding the client's reasons for refusal can guide appropriate interventions, respecting client autonomy while addressing any underlying issues. Choice B is not the best course of action as involving family members may not address the client's specific concerns. Choice C, while important, may not directly address the immediate refusal to bathe. Choice D does not address the underlying reasons for the refusal and may not lead to a resolution.

3. A client is prescribed warfarin for the prevention of thromboembolism. What dietary instruction should the nurse provide?

Correct answer: B

Rationale: The correct answer is B. Maintaining a consistent intake of vitamin K-rich foods is important for patients taking warfarin as it helps keep the effects of the medication stable. Choice A is incorrect because while green leafy vegetables are high in vitamin K, they should not be avoided completely but rather consumed consistently. Choice C is also incorrect as avoiding all foods containing vitamin K can lead to fluctuations in warfarin's effectiveness. Choice D is incorrect as a high-protein diet is not specifically recommended for patients taking warfarin.

4. What safety measure should be implemented when administering chemotherapy?

Correct answer: A

Rationale: When administering chemotherapy, it is crucial to use protective gloves and a gown to protect against exposure to hazardous drugs that can be harmful through skin contact. Choice B is incorrect because chemotherapy medication should be prepared in a designated area to prevent contamination and ensure accurate preparation. Choice C is incorrect as chemotherapy should be administered at the appropriate rate to ensure patient safety and avoid adverse effects. Choice D is incorrect as verifying client identifiers is important for medication administration in general but not a specific safety measure related to chemotherapy administration.

5. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.
