Nursing Elites

1. A nurse is monitoring an older adult female client who had a myocardial infarction (MI) for the development of an acute kidney injury (AKI). Which of the following findings should the nurse identify as indicating an increased risk of AKI?

• A. Magnesium 2.0 mEq/L
• B. Blood urea nitrogen (BUN) 20 mg/dL
• C. Serum Osmolality 290 mOsm/kg H2O
• D. Serum creatinine 1.8 mg/dL

Correct answer: D

Rationale: An elevated serum creatinine level (1.8 mg/dL) is a significant indicator of potential kidney impairment. In acute kidney injury (AKI), serum creatinine levels rise due to decreased kidney function, reflecting the kidneys' inability to effectively filter waste from the blood. Magnesium level, BUN, and serum osmolality are not direct indicators of kidney function or risk of AKI. Magnesium levels are more related to electrolyte balance, BUN can be affected by factors other than kidney function, and serum osmolality reflects the concentration of solutes in the blood, not specifically kidney function.

2. A patient is experiencing shortness of breath. What is the nurse's immediate action?

• A. Assist the patient into a high Fowler's position.
• B. Administer oxygen at 2 liters per minute via nasal cannula.
• C. Encourage the patient to take deep breaths and cough.
• D. Assess the patient's lung sounds.

Correct answer: B

Rationale: Administering oxygen at 2 liters per minute via nasal cannula is the immediate action for a patient experiencing shortness of breath. This intervention helps to improve oxygenation and relieve respiratory distress promptly. Placing the patient in a high Fowler's position (choice A) may also be beneficial but providing oxygen takes precedence in this scenario to address the underlying hypoxemia. Encouraging deep breaths and coughing (choice C) may not be appropriate as the first action, especially without assessing the patient first. Assessing lung sounds (choice D) is essential but should follow the initial intervention of administering oxygen.

3. A nurse is preparing to administer medication to a client by nasogastric tube. What should the nurse do first?

• A. Administer the medication without further assessment.
• B. Check the tube placement before administering any medication.
• C. Administer the medication in liquid form only.
• D. Administer half the dosage as a precaution.

Correct answer: B

Rationale: The correct answer is B: Check the tube placement before administering any medication. Before administering medication through a nasogastric tube, the nurse must first verify the tube's correct placement to ensure the medication reaches the stomach and to prevent complications such as aspiration. Options A, C, and D are incorrect because administering medication without confirming proper tube placement can lead to serious consequences for the client.

4. A nurse is providing discharge teaching to a client following a myocardial infarction (MI). Which of the following activities should the client avoid?

• A. Swimming in a pool
• B. Driving a car
• C. Light housework
• D. Walking on flat ground

Correct answer: B

Rationale: The correct answer is B: Driving a car. Driving a car can be physically and emotionally taxing, increasing the risk of complications soon after a myocardial infarction. It requires quick reflexes and decision-making abilities, which may be impaired during the recovery period. Swimming in a pool, light housework, and walking on flat ground are generally safe and beneficial activities for clients following a myocardial infarction as they promote circulation, muscle strength, and overall well-being.

5. A healthcare provider is reviewing the laboratory report of a client who is receiving heparin therapy for a deep vein thrombosis. Which of the following lab values indicates a therapeutic response to the therapy?

• A. PT of 12 seconds
• B. aPTT of 70 seconds
• C. Platelets of 150,000/mm3
• D. INR of 1.5

Correct answer: B

Rationale: An aPTT of 70 seconds is within the therapeutic range for a client receiving heparin therapy. The activated partial thromboplastin time (aPTT) is the most sensitive test to monitor heparin therapy. A therapeutic aPTT range for a client receiving heparin is usually 1.5 to 2.5 times the control value. Choices A, C, and D are not indicators of a therapeutic response to heparin therapy. PT measures the extrinsic pathway of coagulation and is not specific to monitoring heparin therapy. Platelet count is important to monitor for heparin-induced thrombocytopenia, but it does not indicate the therapeutic response to heparin therapy. INR is used to monitor warfarin therapy, not heparin therapy.
