Nursing Elites

1. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

2. A male client with HIV on antiretroviral therapy complains of constant hunger and thirst while losing weight. What action should the nurse implement?

• A. Check the client's glucose level with a glucometer.
• B. Measure the client's weight accurately.
• C. Reassure the client that weight will stabilize as viral load decreases.
• D. Increase the dose of saquinavir.

Correct answer: A

Rationale: The correct action for the nurse to implement is to check the client's glucose level with a glucometer. Constant hunger and thirst along with weight loss can be indicative of hyperglycemia, a possible side effect of saquinavir. Monitoring the client's glucose levels is crucial in this situation. Measuring the client's weight accurately (Choice B) is important for monitoring purposes but does not address the immediate concern of hunger, thirst, and weight loss. Reassuring the client that weight will stabilize as viral load decreases (Choice C) is not appropriate in this scenario as the symptoms described need immediate attention. Increasing the dose of saquinavir (Choice D) without assessing the client's glucose level can worsen the hyperglycemia.

3. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to lead poisoning?

• A. An 8-year-old who lives in a housing project.
• B. A 2-year-old who plays on aging playground equipment.
• C. An adolescent who works in a paint factory.
• D. A 10-year-old with Type 1 diabetes.

Correct answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are at higher risk of lead poisoning due to their hand-to-mouth behavior and exploration of their environment. Aging playground equipment may have lead-based paint that can be ingested by the child. While children living in housing projects are also at risk due to lead-based paint in older buildings, the 2-year-old child playing on potentially lead-contaminated playground equipment is the most susceptible in this scenario. The adolescent working in a paint factory may face occupational hazards related to lead exposure, but the immediate risk from environmental sources is higher for the 2-year-old. Type 1 diabetes in a 10-year-old is not directly linked to an increased susceptibility to lead poisoning.

4. During an assessment of a client with congestive heart failure, the nurse is most likely to hear which of the following upon auscultation of the heart?

• A. S3 ventricular gallop
• B. Apical click
• C. Systolic murmur
• D. Split S2

Correct answer: A

Rationale: Correct Answer: An S3 ventricular gallop is an abnormal heart sound commonly heard in clients with congestive heart failure. This sound is indicative of fluid overload or volume expansion in the ventricles, which is often present in heart failure. <br> Incorrect Answers: <br> B: An apical click is not typically associated with congestive heart failure. <br> C: A systolic murmur may be heard in various cardiac conditions but is not specific to congestive heart failure. <br> D: A split S2 refers to a normal heart sound caused by the closure of the aortic and pulmonic valves at slightly different times during inspiration, not directly related to congestive heart failure.

5. The client with a below-the-knee amputation is being taught about proper care of the residual limb. The most important point to emphasize would be

• A. Wrap the stump with an elastic bandage to prevent swelling
• B. Keep the skin on the stump clean and dry
• C. Use alcohol to cleanse the stump daily
• D. Apply moisturizing lotion to the stump daily

Correct answer: B

Rationale: The correct answer is B: Keep the skin on the stump clean and dry. This is crucial for preventing infection and promoting healing of the residual limb. Wrapping the stump with an elastic bandage can constrict blood flow and cause issues. Using alcohol to cleanse the stump daily can be too harsh and drying for the skin, leading to irritation. Applying moisturizing lotion daily is not as essential as keeping the skin clean and dry to prevent complications.
