Nursing Elites

1. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.

2. The nurse is caring for a client following a myelogram. Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Complaint of headaches and stiff neck.
• B. Complaint of dizziness and nausea.
• C. Increased pain at the puncture site.
• D. Mild redness around the puncture site.

Correct answer: A

Rationale: The correct answer is A: Complaint of headaches and stiff neck. Headaches and stiff neck following a myelogram may indicate a cerebrospinal fluid (CSF) leak or other complications that require prompt medical attention. Reporting this finding immediately is crucial to prevent further complications. Choices B, C, and D are incorrect because while they may warrant monitoring and intervention, they are not as indicative of a potentially serious complication as the symptoms described in choice A.

3. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?

• A. Widening QRS complexes and flat T waves
• B. Tachycardia and elevated blood pressure
• C. Restlessness and anxiety
• D. Diaphoresis and dehydration

Correct answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.

4. The nurse is caring for a client with chronic kidney disease (CKD). Which laboratory value should be reported to the healthcare provider immediately?

• A. Serum creatinine of 2.0 mg/dl
• B. Hemoglobin of 10 g/dl
• C. Potassium of 6.5 mEq/L
• D. Blood glucose of 150 mg/dl

Correct answer: C

Rationale: The correct answer is C. A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, and requires immediate intervention to prevent cardiac complications. Hyperkalemia can lead to life-threatening arrhythmias, making it crucial to notify the healthcare provider promptly. Choices A, B, and D do not indicate immediate life-threatening conditions. Elevated serum creatinine levels are expected in CKD, a hemoglobin level of 10 g/dl is within a reasonable range, and a blood glucose level of 150 mg/dl is not acutely concerning in this context.

5. When preparing to insert a nasogastric (NG) tube for a client admitted to the surgical unit with symptoms of a possible intestinal obstruction, which intervention should the nurse implement?

• A. Elevate the head of the bed 60 to 90 degrees
• B. Administer an antiemetic
• C. Prepare the client for surgery
• D. Provide oral care

Correct answer: A

Rationale: Elevating the head of the bed to 60 to 90 degrees is essential when inserting an NG tube. This position helps facilitate the passage of the tube through the esophagus into the stomach and reduces the risk of aspiration. Administering an antiemetic may be necessary to control nausea or vomiting, but it is not the primary intervention when inserting an NG tube. Preparing the client for surgery is not indicated solely for the insertion of an NG tube. Providing oral care is important for maintaining oral hygiene but is not directly related to inserting an NG tube.
