1. At a mobile screening clinic, a nurse is assessing a client who reports a history of a heart murmur due to aortic stenosis. To auscultate the aortic valve, where should the nurse place the stethoscope?
- A. Second intercostal space to the right of the sternum
- B. Fifth intercostal space to the left of the sternum
- C. Third intercostal space to the left of the sternum
- D. Fourth intercostal space at the midclavicular line
Correct answer: A
Rationale: The correct location to auscultate the aortic valve is the second intercostal space to the right of the sternum. This area corresponds to the aortic valve area where aortic valve sounds are best heard. Choices B, C, and D are incorrect for auscultating the aortic valve. The fifth intercostal space to the left of the sternum is where the mitral valve is best heard, the third intercostal space to the left of the sternum is where the pulmonic valve is best heard, and the fourth intercostal space at the midclavicular line is where the tricuspid valve is best auscultated.
2. When assessing a client's skin turgor, a nurse should:
- A. Grasp a fold of the skin on the chest under the clavicle, release it, and note the depth of the impression
- B. Check skin elasticity on the back of the hand
- C. Press on the skin over the abdomen
- D. Measure skin turgor on the lower leg
Correct answer: A
Rationale: Correct answer: When assessing a client's skin turgor, a nurse should grasp a fold of the skin on the chest under the clavicle, release it, and note the depth of the impression. This method is reliable for evaluating hydration status as it is less influenced by age-related skin changes or adipose tissue. Choice B, checking skin elasticity on the back of the hand, is not the preferred method for assessing skin turgor. Choice C, pressing on the skin over the abdomen, is not a standard location for assessing skin turgor. Choice D, measuring skin turgor on the lower leg, is not a recommended site for assessing skin turgor in clinical practice.
3. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?
- A. 8 mL/hr
- B. 10 mL/hr
- C. 12 mL/hr
- D. 15 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
4. A client is reporting difficulty falling asleep. Which of the following measures should the nurse recommend?
- A. Drink a cup of hot cocoa before bedtime
- B. Exercise 1 hour before going to bed
- C. Use progressive relaxation techniques at bedtime
- D. Reflect on the day's activities before going to bed
Correct answer: C
Rationale: The correct answer is to recommend the client to use progressive relaxation techniques at bedtime. Progressive relaxation techniques help reduce stress and muscle tension, which can promote better sleep. Choice A, drinking a cup of hot cocoa before bedtime, contains caffeine which can interfere with falling asleep. Choice B, exercising 1 hour before going to bed, can stimulate the body and mind, making it harder to fall asleep. Choice D, reflecting on the day's activities before going to bed, may lead to increased mental activity and prevent relaxation, making it difficult to fall asleep.
5. A healthcare professional is reviewing a client’s medications. They include cimetidine and imipramine. Knowing that cimetidine decreases the metabolism of imipramine, the healthcare professional should identify that this combination is likely to result in which of the following effects?
- A. Decreased therapeutic effects of cimetidine
- B. Increased risk of imipramine toxicity
- C. Decreased risk of adverse effects of cimetidine
- D. Increased therapeutic effects of imipramine
Correct answer: B
Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.
