Question 1 of 5
A client with congestive heart failure (CHF) experiences worsening dyspnea and peripheral edema. What is the primary indication for initiating oxygen therapy in this client?
Correct Answer: D
Rationale: Improving myocardial oxygenation (D) is the primary indication for oxygen therapy in CHF with worsening dyspnea, addressing myocardial ischemia from low oxygen supply. Reducing heart workload (A) is a benefit, not the goal. Edema (B) and fluid overload (C) require diuretics, not oxygen. Enhanced cardiac oxygenation supports pump function, per cardiology standards, critical in acute CHF exacerbations.
Question 2 of 5
The client scheduled for electroconvulsive therapy tells the nurse, 'I'm so afraid. What will happen to me during the treatment?' Which of the following statements is most therapeutic for the nurse to make?
Correct Answer: A
Rationale: Saying, 'You will be given medicine to relax you during the treatment,' is most therapeutic, addressing fear with reassurance about comfort and safety during electroconvulsive therapy (ECT), a common anxiety for clients. Detailing seizures, side effects, or post-treatment confusion might heighten fear rather than soothe it. Nurses use this approach to build trust, easing emotional distress while preparing clients for the procedure effectively.
Question 3 of 5
The nurse calculates the amount of an antibiotic for injection to be given to an infant. The amount of medication to be administered is 1.25mL. The nurse should:
Correct Answer: A
Rationale: For an infant, 1.25mL exceeds the 0.5-1mL per-site limit for small muscles, so dividing it into two 0.625mL injections in each vastus lateralis ensures safe absorption without tissue damage. Dorsogluteal and ventrogluteal sites are risky or underdeveloped in infants. Nurses split doses this way, using preferred sites to minimize pain and optimize delivery, critical for pediatric dosing.
Question 4 of 5
A client with hypothyroidism is prescribed Synthroid (levothyroxine). The nurse should tell the client to take the medication:
Correct Answer: C
Rationale: Synthroid (levothyroxine) should be taken 30 minutes before breakfast on an empty stomach, maximizing absorption for hypothyroidism treatment, as food especially calcium or iron reduces uptake, per endocrine guidelines. Meal timing or bedtime dosing lowers efficacy. Nurses instruct this timing, ensuring consistent thyroid hormone levels, improving energy, metabolism, and symptom control for the client.
Question 5 of 5
The physician has ordered a culture for HBsAg for a client with suspected hepatitis. The nurse should:
Correct Answer: B
Rationale: Collecting an HBsAg culture (blood test for hepatitis B surface antigen) in a sterile container ensures accurate viral detection IV sites, fasting, or NG tubes don't apply to serology. Nurses use this method, avoiding contamination, aiding swift diagnosis of liver infection.
