1. A home health care nurse is visiting a client with elevated triglyceride levels and a serum cholesterol level of 398 mg/dL. The client is taking cholestyramine (Questran). Which of the following statements, if made by the client, indicates the need for further education?
- A. Constipation and bloating might be a problem.
- B. I'll continue to watch my diet and reduce my fats.
- C. Walking a mile each day will help the whole process.
- D. I'll continue my nicotinic acid from the health food store.
Correct answer: D
Rationale: Nicotinic acid, even an over-the-counter form, should be avoided because it may lead to liver abnormalities. All lipid-lowering medications also can cause liver abnormalities, so a combination of nicotinic acid and cholestyramine resin is to be avoided. Constipation and bloating are the two most common side effects. Walking and the reduction of fats in the diet are therapeutic measures to reduce cholesterol and triglyceride levels.
2. A client receiving codeine for pain every 4 to 6 hours over 4 days. Which assessment should the nurse perform before administering the next dose?
- A. Auscultate the bowel sounds.
- B. Palpate the ankles for edema.
- C. Observe the skin for bruising.
- D. Measure the body temperature.
Correct answer: A
Rationale: The correct answer is A: Auscultate the bowel sounds. Codeine is known to cause constipation, so it is essential to assess bowel sounds before administering another dose to monitor for potential constipation or bowel motility issues. Palpating the ankles for edema (Choice B) is not directly related to codeine use or its side effects. Observing the skin for bruising (Choice C) is important but not specifically associated with codeine administration. Measuring body temperature (Choice D) is not a priority assessment related to codeine use; monitoring for constipation is more critical in this case.
3. In meiosis, the chromosome number is reduced from:
- A. 46 to 23
- B. 46 to 33
- C. 28 to 14
- D. 24 to 12
Correct answer: A
Rationale: The correct answer is A: "46 to 23." In meiosis, the chromosome number is reduced by half to form gametes for sexual reproduction. In humans, where the diploid chromosome number is 46, meiosis results in haploid cells with 23 chromosomes. Choices B, C, and D are incorrect because they do not represent the correct reduction in chromosome number during meiosis.
4. Which lab result would be most indicative of renal failure?
- A. Elevated creatinine levels.
- B. Low potassium levels.
- C. Low calcium levels.
- D. High sodium levels.
Correct answer: A
Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.
5. A client has undergone insertion of a permanent pacemaker. When developing a discharge teaching plan, the nurse writes a goal of, 'The client will verbalize symptoms of pacemaker failure.' Which symptoms are most important to teach the client?
- A. Facial flushing.
- B. Fever.
- C. Pounding headache.
- D. Feelings of dizziness.
Correct answer: D
Rationale: The correct answer is 'D: Feelings of dizziness.' Feelings of dizziness may occur as a result of a decreased heart rate, leading to decreased cardiac output, which can be an indication of pacemaker failure. Teaching the client to recognize symptoms of decreased cardiac output, like dizziness, is crucial for early detection of pacemaker malfunction. Choices A, B, and C are less specific to pacemaker failure and are not commonly associated with this condition. Facial flushing, fever, and pounding headache are not typical signs of pacemaker failure and are not directly related to cardiac output, making them less relevant for teaching the client about pacemaker failure.
