1. The nurse is caring for a client who is postoperative following a thyroidectomy. Which laboratory value should be monitored closely?
- A. Serum calcium of 8.5 mg/dL
- B. Serum sodium of 136 mEq/L
- C. Serum potassium of 3.0 mEq/L
- D. Serum chloride of 102 mEq/L
Correct answer: C
Rationale: A serum potassium level of 3.0 mEq/L should be monitored closely in a client who is postoperative following a thyroidectomy to detect any electrolyte imbalances. After a thyroidectomy, there is a risk of hypokalemia due to the effects of anesthesia, stress response, and the surgical procedure itself. Monitoring serum potassium levels is crucial as hypokalemia can lead to cardiac arrhythmias and muscle weakness. Serum calcium, sodium, and chloride levels are important but not the primary focus following a thyroidectomy, making them incorrect choices.
2. 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.
3. James is a 42-year-old patient with schizophrenia. He approaches you as you arrive for day shift and anxiously reports, 'Last night, demons came to my room and tried to rape me.' Which response would be most therapeutic?
- A. There are no such things as demons. What you saw were hallucinations.
- B. It is not possible for anyone to enter your room at night. You are safe here.
- C. You seem very upset. Please tell me more about what you experienced last night.
- D. That must have been very frightening, but we will check on you at night and you will be safe.
Correct answer: C
Rationale: Choice C is the most therapeutic response as it acknowledges the patient's feelings and encourages further exploration of their experience. By expressing empathy and inviting James to share more about what he experienced, it helps build trust and rapport. Choices A and B dismiss the patient's experience and can make them feel invalidated, which is not helpful in establishing a therapeutic relationship. Choice D acknowledges the fear but does not actively engage the patient in discussing their feelings and experiences, missing an opportunity for therapeutic communication.
4. How do contraceptive oral pills help in birth control?
- A. Preventing ovulation
- B. Killing ova
- C. Killing sperms
- D. More than one of the above
Correct answer: A
Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.
5. The healthcare provider is assessing a client who has a new arteriovenous fistula in the left arm for hemodialysis. Which finding requires immediate intervention?
- A. A thrill is palpable on the fistula.
- B. The client's arm is warm and red.
- C. The fistula has a bruit on auscultation.
- D. There is no bruit on auscultation.
Correct answer: B
Rationale: The correct answer is B. Warmth and redness in the client's arm suggest infection or thrombosis of the arteriovenous fistula, which requires immediate intervention to prevent complications. A thrill (A) is a normal finding in a functional arteriovenous fistula, indicating good blood flow. A bruit (C) is also a normal finding on auscultation of a functioning arteriovenous fistula, indicating proper blood flow. The absence of a bruit (D) may indicate a non-functioning fistula, which would need further evaluation but does not require immediate intervention as warmth and redness do.
