Nursing Elites

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. A nurse is caring for a client who has a surgical wound. Which of the following laboratory values places the client at risk for poor wound healing?

• A. Serum albumin 3 g/dL
• B. Total lymphocyte count 2400/mm3
• C. HCT 42%
• D. HGB 16 g/dL

Correct answer: A

Rationale: The correct answer is A: Serum albumin 3 g/dL. Low levels of serum albumin indicate poor nutritional status and can impair wound healing. Total lymphocyte count, HCT, and HGB levels are not directly related to wound healing and do not pose a significant risk for poor wound healing in this context. Total lymphocyte count reflects the immune status, HCT measures the percentage of red blood cells in blood, and HGB measures the amount of hemoglobin in blood.

3. A client has right-sided paralysis following a cerebrovascular accident. Which of the following prescriptions should the nurse anticipate to prevent a plantar flexion contracture of the affected extremity?

• A. Ankle-foot orthotic
• B. Continuous passive motion machine
• C. Abduction splint
• D. Sequential compression device

Correct answer: A

Rationale: An ankle-foot orthotic is the correct choice to prevent a plantar flexion contracture in a paralyzed limb. An ankle-foot orthotic helps maintain proper alignment of the foot and ankle, preventing the foot from being permanently fixed in a pointed-down position. Continuous passive motion machines are typically used to promote joint movement after surgery and would not address the prevention of contractures in this case. Abduction splints are used to keep the legs apart and would not address the specific issue described. Sequential compression devices are used to prevent deep vein thrombosis by promoting circulation in the lower extremities and are not indicated for preventing plantar flexion contractures.

4. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hours. The healthcare professional should set the pump to deliver how many mL/hr?

• A. 107 mL/hr
• B. 75 mL/hr
• C. 90 mL/hr
• D. 60 mL/hr

Correct answer: A

Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL ÷ 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.

5. During a follow-up visit, a home health nurse notices that a client with a gastrostomy tube, who receives intermittent feedings and medications, has developed diarrhea. Which of the following findings should the nurse identify as a possible cause of the diarrhea?

• A. The client’s caregiver washes out the feeding bag once every 24 hours with warm water.
• B. The client’s caregiver washes out the feeding bag with hot water every 24 hours.
• C. The client’s caregiver changes the feeding bag every 48 hours.
• D. The client’s caregiver adds water to the formula before administration.

Correct answer: A

Rationale: The correct answer is A. Washing out the feeding bag once every 24 hours with warm water can lead to bacterial growth due to inadequate cleaning, potentially causing diarrhea. Hot water, as in choice B, can also promote bacterial growth, which is not desirable. Changing the feeding bag every 48 hours, like in choice C, is within an acceptable timeframe and is unlikely to be a cause of diarrhea. Adding water to the formula before administration, as in choice D, is a common practice to dilute the formula but is not typically associated with causing diarrhea in this scenario.
