Correct Answer: B

Rationale: The correct answer is B because cleaning the hearing aids with alcohol wipes can damage them. It is important to use specialized cleaning tools or follow specific cleaning instructions provided by the manufacturer to prevent harm to the hearing aids. Choices A, C, and D demonstrate good understanding and appropriate care for hearing aids, indicating that the client does not need further instruction in those areas.

Correct Answer: C

Rationale: The correct answer is C: 'Breath sounds.' When providing a change-of-shift report for a client with pneumonia, the priority information to communicate is the assessment of breath sounds. Monitoring breath sounds is crucial in assessing respiratory status and the effectiveness of treatments in pneumonia. Option A, recent chest x-ray results, may be important but does not provide real-time information on the client's current status. Option B, medication history, is relevant but not as immediate as assessing breath sounds. Option D, lab results, can provide valuable information but may not be as urgent as monitoring the client's respiratory status through breath sounds.

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.

Correct Answer: B

Rationale: Evaluating electrolytes is crucial when addressing fluid overload as it helps determine the severity of the imbalance and guides treatment. Assessing for edema (Choice A) is important but not the priority over evaluating electrolytes. Restricting fluid intake (Choice C) and administering diuretics (Choice D) are interventions that may be necessary but should be based on the electrolyte evaluation to ensure safe and effective care.

Correct Answer: B

Rationale: Verifying the patient's identity before administration is a critical step to ensure that the correct blood product is given to the right patient, thereby preventing transfusion errors. While ensuring proper documentation of the transfusion (choice A) is important for record-keeping, verifying patient identity (choice B) directly addresses the risk of administering blood to the wrong patient. Monitoring for allergic reactions or transfusion reactions (choice C) and monitoring the patient's vital signs during transfusion (choice D) are also essential considerations during blood product administration, but verifying patient identity takes precedence to prevent potentially life-threatening errors.
