Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?

• A. Place the client in a side-lying position
• B. Instill 15 mL of irrigation fluid into the catheter with each flush
• C. Subtract the amount of irrigant used from the client's urine output
• D. Perform the irrigation using a 20 mL syringe

Correct answer: C

Rationale: The correct action for the nurse to take when using an open irrigation technique on a client with an indwelling urinary catheter is to subtract the amount of irrigant used from the client's urine output. This calculation helps ensure an accurate measurement of the client's actual urine output by accounting for the irrigation fluid introduced into the catheter. Placing the client in a side-lying position (Choice A) is not directly related to the irrigation procedure. Instilling a specific volume of irrigation fluid (Choice B) may vary depending on the client's condition and the healthcare provider's order. Using a 20 mL syringe for irrigation (Choice D) is a matter of equipment choice and does not directly impact the calculation of urine output in this context.

3. What advice should the client be given if they are feeling dizzy upon standing after taking a diuretic for hypertension?

• A. Avoid standing up too quickly.
• B. Increase fluid intake to stay hydrated.
• C. Eat more salt to help retain fluids.
• D. Wear compression stockings during the day.

Correct answer: A

Rationale: The correct advice for a client feeling dizzy upon standing after taking a diuretic for hypertension is to avoid standing up too quickly. Diuretics can lead to orthostatic hypotension, causing dizziness upon sudden position changes. Increasing fluid intake can exacerbate the issue by further lowering blood pressure. Eating more salt might counteract the diuretic's effects but is not the primary intervention for orthostatic hypotension. Compression stockings are more relevant for venous insufficiency than for orthostatic hypotension.

4. The female is caring for a male patient who is uncircumcised but not ambulatory and has full function of all extremities. The nurse is providing the patient with a partial bed bath. How should perineal care be performed for this patient?

• A. Should be postponed because it may cause embarrassment.
• B. Should be unnecessary because the patient is uncircumcised.
• C. Should be done by the patient.
• D. Should be done by the nurse.

Correct answer: C

Rationale: Perineal care should be encouraged to be done by the patient if they are capable of performing self-care. In this scenario, the patient is not ambulatory and has full function of all extremities, indicating that the patient can independently perform perineal care. Encouraging self-care promotes independence and maintains the patient's dignity. Postponing perineal care (Choice A) is incorrect because it is essential for hygiene. Choice B is incorrect as perineal care is necessary for all patients regardless of circumcision status. Choice D is incorrect as the patient is capable of performing the care independently, and promoting self-care is a priority in nursing practice.

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.
