Correct Answer: B

Rationale: An HbA1c of 7.0% in a client with diabetes mellitus indicates poor long-term glucose control, necessitating immediate follow-up. Elevated HbA1c levels suggest a higher average blood sugar over the past 2-3 months, increasing the risk of complications associated with diabetes. Choices A, C, and D do not require immediate follow-up based solely on the provided information. A serum creatinine of 1.6 mg/dL in a client with chronic kidney disease, a BNP of 140 pg/mL in a client with heart failure, and hemoglobin of 16.5 g/dL and hematocrit of 45% in a male client with anemia are within acceptable ranges or do not indicate an urgent need for intervention.

Correct Answer: B

Rationale: The correct answer is B, Steroids. Steroids are known to cause weight gain as a side effect. Amphetamines, choice A, are more likely to cause appetite suppression and weight loss. Antibiotics, choice C, and nonsteroidal anti-inflammatory drugs, choice D, are not typically associated with weight gain as a common side effect.

Correct Answer: B

Rationale: The correct action for the nurse to take when there is a pause after the machine is activated during synchronized cardioversion is to shout "all clear" and ensure that no one is touching the client or the bed to prevent them from being shocked. This step is crucial for the safety of everyone present during the procedure. Choices A, C, and D are incorrect because waiting without confirming safety, focusing on the client's condition only, or increasing joules without safety precautions can lead to potential harm or injury.

Correct Answer: C

Rationale: The correct question the nurse should ask the mother before administering an MMR vaccine to a 15-month-old is whether the child is allergic to any antibiotics. This is crucial because vaccines like MMR contain components that the child could be allergic to, such as neomycin. Checking for antibiotic allergies is essential to prevent adverse reactions to the vaccine. The other options are less relevant in this context. Asking about sore throats, eating habits, or exposure to infections does not directly impact the administration of the MMR vaccine.

Correct Answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.
