Exam Cram NCLEX RN Practice Questions

1. A home care nurse instructs the mother of a 5-year-old child with lactose intolerance about dietary measures for her child. The nurse should tell the mother that it is necessary to provide which dietary supplement in the child's diet?

A. Fats
B. Zinc
C. Protein
D. Calcium

Correct answer: D

Rationale: In lactose intolerance, the inability to digest lactose, the sugar in dairy products, can lead to calcium deficiency if dairy products are removed from the diet. Calcium is crucial for bone health and other bodily functions, so alternative calcium sources like fortified non-dairy milks or leafy greens must be included to prevent deficiency. While fats and proteins are important nutrients, they are not typically deficient in lactose intolerance. Zinc, although an essential mineral, is not the primary concern in this case.

2. A patient is undergoing a stress test on a treadmill and turns to talk to the nurse. Which of these statements would require the most immediate intervention?

A. I'm feeling extremely thirsty and will get some water after this.
B. I can feel my heart racing.
C. My shoulder and arm are hurting.
D. My blood pressure reading is 158/80

Correct answer: C

Rationale: The correct answer is 'C: My shoulder and arm are hurting.' Unilateral arm and shoulder pain are classic symptoms of myocardial ischemia, indicating possible heart issues. In this scenario, immediate intervention is required, and the stress test should be halted. Choice A about feeling thirsty does not indicate an acute medical issue. Choice B mentioning heart racing is expected during a stress test. Choice D, a blood pressure reading of 158/80, while slightly elevated, does not present an immediate concern compared to the symptoms of arm and shoulder pain suggesting cardiac distress.

3. Which clinical manifestations are recognized in nephrotic syndrome?

A. Hematuria, bacteriuria, weight gain
B. Gross hematuria, albuminuria, fever
C. Hypertension, weight loss, proteinuria
D. Massive proteinuria, hypoalbuminemia, edema

Correct answer: D

Rationale: Nephrotic syndrome is characterized by massive proteinuria, hypoalbuminemia, and edema. In this syndrome, there is loss of proteins, particularly albumin, in the urine leading to hypoalbuminemia, fluid retention, and subsequent edema. This results in elevated lipid levels like hypercholesterolemia, but not hypertension. Therefore, choices A, B, and C are incorrect. Hematuria, bacteriuria, fever, and weight loss are not typically associated with nephrotic syndrome, distinguishing it from other kidney disorders.

4. Which response would best assist the chemically impaired client in dealing with issues of guilt?

A. Addiction usually causes people to feel guilty. Don't worry, it is a typical response due to your drinking behavior.
B. What have you done that you feel most guilty about and what steps can you begin to take to help you lessen this guilt?
C. Don't focus on your guilty feelings. These feelings will only lead you to drinking and taking drugs.
D. You've caused a great deal of pain to your family and close friends, so it will take time to undo all the things you've done.

Correct answer: B

Rationale: The correct response is, 'What have you done that you feel most guilty about and what steps can you begin to take to help you lessen this guilt?' This response encourages the client to reflect on their actions, identify sources of guilt, and develop a plan to address and reduce these feelings constructively. Choice A is incorrect as it dismisses the client's guilt as typical, potentially invalidating their emotions. Choice C is incorrect as it suggests avoiding guilty feelings by turning to substance use, which is counterproductive. Choice D is incorrect as it focuses on the negative consequences of the client's actions without offering a constructive way to address and alleviate guilt.

5. A client is receiving digoxin (Lanoxin) 0.25 mg daily. The health care provider has written a new order to give metoprolol (Lopressor) 25 mg B.I.D. In assessing the client prior to administering the medications, which of the following should the nurse report immediately to the health care provider?

A. Blood pressure 94/60 mm Hg
B. Heart rate 76 bpm
C. Urine output 50 ml/hour
D. Respiratory rate 16 bpm

Correct answer: A

Rationale: The correct answer is 'Blood pressure 94/60 mm Hg.' Both digoxin and metoprolol decrease the heart rate. Metoprolol specifically affects blood pressure. Therefore, the heart rate and blood pressure need to be within normal range (HR 60-100 bpm; systolic BP above 100 mm Hg) to safely administer both medications. A blood pressure of 94/60 mm Hg indicates hypotension, which could be exacerbated by metoprolol, necessitating immediate reporting to the healthcare provider. Choices B, C, and D are within normal limits and do not pose immediate risks related to the administration of these medications.
