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. A client with heart failure is receiving digoxin (Lanoxin) and furosemide (Lasix). Which assessment finding requires immediate intervention?

• A. Heart rate of 60 beats per minute
• B. Apical pulse of 58 beats per minute
• C. Presence of a new murmur
• D. Blood pressure of 100/60 mmHg

Correct answer: C

Rationale: The correct answer is C. The presence of a new murmur in a client with heart failure receiving digoxin and furosemide is concerning as it may indicate valvular problems or other complications that require immediate intervention. A heart rate of 60 beats per minute and an apical pulse of 58 beats per minute are within normal limits for a client with heart failure on these medications. A blood pressure of 100/60 mmHg, while slightly low, may be expected due to the diuretic effect of furosemide and may not require immediate intervention unless the client is symptomatic.

3. The nurse teaches an adolescent male client how to use a metered dose inhaler. What instruction should the nurse provide?

• A. Secure the mouthpiece under the tongue.
• B. Press down on the device after breathing in fully.
• C. Move the device one to two inches away from the mouth.
• D. Breathe out slowly and deeply while compressing the device.

Correct answer: C

Rationale: The correct instruction for using a metered dose inhaler is to move the device one to two inches away from the mouth. This distance helps ensure effective delivery of the medication directly to the airways. Choice A is incorrect as the mouthpiece should be placed between the lips, not under the tongue. Choice B is incorrect because the device should be pressed down before breathing in, not after. Choice D is wrong because the patient should breathe out fully before using the inhaler, not while compressing the device.

4. The nurse is reinforcing home care instructions with a client who is being discharged following a transurethral resection of the prostate (TURP). Which intervention is most important for the nurse to include in the client teaching?

• A. Avoid strenuous activity for 6 weeks.
• B. Report fresh blood in the urine.
• C. Take acetaminophen for a fever over 101°F.
• D. Consume 6 to 8 glasses of water daily.

Correct answer: B

Rationale: Reporting fresh blood in the urine is crucial as it may indicate postoperative complications requiring immediate attention. This symptom can be a sign of bleeding, infection, or other issues that need prompt medical evaluation. Avoiding strenuous activity for 6 weeks is important but not as urgent as reporting fresh blood. Taking acetaminophen for a fever over 101°F is relevant but addressing fresh blood in the urine takes precedence. Consuming an adequate amount of water daily is beneficial but not as critical as recognizing and reporting signs of potential complications.

5. A client with a history of coronary artery disease (CAD) is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of CAD and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify signs of ischemia or a heart attack. While other diagnostic tests like chest X-ray, arterial blood gases, and echocardiogram may also be necessary in the evaluation of chest pain, they do not provide the initial direct assessment of cardiac ischemia that an ECG does.
