1. A nurse is caring for a child who has cystic fibrosis and is receiving postural drainage. Which of the following actions should the nurse take?

Correct answer: C

Rationale: The correct action the nurse should take when caring for a child with cystic fibrosis receiving postural drainage is to hold the hand flat to perform percussion. This technique allows for effective chest physiotherapy. Choice A is incorrect because postural drainage should be performed before meals to prevent vomiting during the procedure. Choice B is incorrect because bronchodilators are typically administered before postural drainage to help open up the airways. Choice D is incorrect as the frequency of postural drainage may vary depending on the individual's condition, so performing it twice a day may not be appropriate for all patients.

2. A male patient is being treated with sildenafil (Viagra) for erectile dysfunction. What condition would contraindicate the use of this medication?

Correct answer: D

Rationale: The correct answer is D: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, and the combination can lead to a dangerous drop in blood pressure. Choice A, peptic ulcer disease, is not a contraindication for sildenafil use. Choice B, a history of myocardial infarction, is not a contraindication unless the patient is also taking nitrates. Choice C, recent use of antihypertensive medications, is not a contraindication but requires caution as the combination can lead to additive effects lowering blood pressure.

3. A client with a new diagnosis of hypertension is being taught by a nurse. Which of the following statements by the client indicates an understanding of the teaching?

Correct answer: C

Rationale: The correct answer is C. Clients with hypertension should avoid salt substitutes because they often contain potassium, which can raise potassium levels. Choice A is incorrect as decreasing potassium intake is not necessary unless advised by a healthcare provider. Choice B is incorrect as not all clients with hypertension need to take medication for life. Choice D is incorrect as grapefruit juice does not significantly impact hypertension management.

4. A client who is at 10 weeks of gestation is being taught about nutrition during pregnancy. Which statement by the client indicates an understanding of the teaching?

Correct answer: B

Rationale: The correct answer is B. Increasing folic acid intake is crucial during pregnancy to prevent neural tube defects. Option A is incorrect because calorie requirements during pregnancy vary and are generally higher than 1,200 calories per day. Option C is not specific to pregnancy nutrition teaching, although hydration is important. Option D is incorrect as iron-rich foods are typically recommended during pregnancy to prevent anemia.

5. A patient with hypertension is taking an ACE inhibitor to lower blood pressure. What should the nurse advise the patient to avoid in their diet?

Correct answer: C

Rationale: Patients taking ACE inhibitors should avoid salt substitutes as they often contain potassium, which can lead to hyperkalemia. Hyperkalemia is an elevated level of potassium in the blood that can be dangerous, especially for patients on ACE inhibitors. Vinegar, apples, and tomatoes do not pose a risk for patients taking ACE inhibitors. Therefore, the nurse should advise the patient to avoid salt substitutes to prevent potential complications.
