1. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?
- A. Mental retardation occurs if PKU is untreated.
- B. Testing for PKU is done immediately after birth.
- C. Treatment for PKU includes lifelong dietary management.
- D. PKU is transmitted by an autosomal recessive gene.
Correct answer: A
Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that, if left untreated with dietary management, can lead to severe mental retardation due to the accumulation of phenylalanine. It is crucial for parents to understand the potential consequences of untreated PKU to emphasize the importance of early and consistent treatment. Choice B is incorrect because testing for PKU is typically done through newborn screening shortly after birth, not immediately. Choice C is incorrect as treatment for PKU primarily involves strict dietary management that restricts phenylalanine intake, not lifelong medications. Choice D is incorrect as PKU is inherited in an autosomal recessive pattern, meaning that both parents must pass on a mutated gene for the disorder to manifest.
2. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
3. A healthcare professional is preparing to administer metoprolol 200 mg PO daily. The medication available is metoprolol 100 mg/tablet. How many tablets should the healthcare professional administer? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 1 tablet
- B. 2 tablets
- C. 0.5 tablet
- D. 4 tablets
Correct answer: B
Rationale: To administer 200 mg of metoprolol using 100 mg tablets, the healthcare professional should give 2 tablets. Each tablet contains 100 mg of metoprolol, so 2 tablets will provide the required 200 mg dose. Choice A is incorrect because 1 tablet would only provide 100 mg, which is insufficient. Choice C is incorrect as fractions of tablets are usually not used in practice to ensure accurate dosing. Choice D is incorrect as it would result in an overdose, providing 400 mg instead of the prescribed 200 mg.
4. A client who is 24 weeks pregnant presents with a complaint of feeling dizzy when lying on her back. What is the best response by the nurse?
- A. Advise the client to lie on her side
- B. Encourage the client to drink more fluids
- C. Suggest the client elevate her legs when lying down
- D. Recommend the client take short walks throughout the day
Correct answer: A
Rationale: The correct answer is to advise the client to lie on her side. Lying on the side can prevent the compression of the vena cava, which can cause dizziness in pregnant women. Encouraging the client to drink more fluids (Choice B) may be beneficial for other conditions but is not the best response for dizziness when lying on her back. Suggesting the client elevate her legs when lying down (Choice C) is not directly related to the issue described by the client. Recommending the client take short walks throughout the day (Choice D) may be helpful for other pregnancy-related symptoms but is not the most appropriate action for dizziness when lying on her back.
5. A client with depression reports difficulty sleeping. What is the most appropriate nursing intervention?
- A. Encourage the client to take short naps during the day.
- B. Suggest the client drink a warm beverage before bedtime.
- C. Recommend the client exercise immediately before bedtime.
- D. Advise the client to take a sleep aid nightly.
Correct answer: B
Rationale: The most appropriate nursing intervention for a client with depression reporting difficulty sleeping is to suggest the client drink a warm beverage before bedtime. A warm beverage can promote relaxation and help establish a bedtime routine, which may aid in improving sleep quality. Encouraging short naps during the day (Choice A) may disrupt the client's nighttime sleep pattern. Recommending exercise immediately before bedtime (Choice C) can have a stimulating effect, making it harder for the client to fall asleep. Advising the client to take a sleep aid nightly (Choice D) should only be considered after other non-pharmacological interventions have been attempted and in consultation with a healthcare provider due to potential side effects and risks associated with sleep aids.
