During a home visit, the nurse observes that an elderly client has numerous bruises on her arms and appears fearful of her caregiver. What should the nurse do first?

Correct Answer: B

Rationale: The initial step for the nurse should be to ask the client how she got the bruises. This approach allows the nurse to directly assess the situation, gather information from the client, and potentially uncover signs of abuse. Reporting to adult protective services should come after obtaining more details from the client to ensure appropriate action. Documenting the observations is important but should follow gathering information from the client. Discussing the observations with the caregiver may not be appropriate as the caregiver could be the source of abuse, and involving them first may jeopardize the client's safety.

Correct Answer: D

Rationale: The correct answer is D, the serum ammonia level of 180 mcg/dL. An elevated serum ammonia level indicates hepatic dysfunction and can lead to hepatic encephalopathy, which is a medical emergency requiring immediate intervention. Options A, B, and C are within normal ranges or slightly abnormal values for clients with cirrhosis and do not pose an immediate threat. Serum albumin levels may indicate malnutrition, prothrombin time may reflect liver synthetic function, and hemoglobin levels can be affected by various factors but do not require immediate intervention in this scenario.

Correct Answer: C

Rationale: The correct answer is C. Sudden severe abdominal pain is a key clinical manifestation of a perforated ulcer. The sudden onset of severe pain is concerning for a perforation in the ulcer, which can lead to peritonitis if not promptly addressed. Choices A, B, and D are incorrect because hyperactive bowel sounds, a soft and nondistended abdomen, and a blood pressure of 110/70 mm Hg are not specific indicators of a perforated ulcer. Hyperactive bowel sounds may suggest increased gastrointestinal motility, a soft abdomen may not necessarily indicate a perforation, and a blood pressure of 110/70 mm Hg is within normal limits and does not directly relate to a perforated ulcer.

Correct Answer: C

Rationale: Decreased urine output in a client receiving total parenteral nutrition (TPN) requires immediate intervention because it can indicate potential complications such as fluid overload or kidney dysfunction. Monitoring urine output is crucial in assessing renal function and fluid balance in patients on TPN. A blood glucose level of 150 mg/dL is within a normal range and may not require immediate intervention. Weight gain of 2 pounds in 24 hours could be a concern but may not be as urgent as addressing decreased urine output. A temperature of 100.3°F (37.9°C) is slightly elevated but may not be directly related to TPN administration unless there are other symptoms of infection present.

Correct Answer: C

Rationale: The correct answer is C. Insulin should not be stored in the refrigerator at all times; it should be kept at room temperature when in use to avoid irritation at the injection site. Storing insulin in the refrigerator can cause it to thicken and may lead to discomfort upon injection. Choices A and D are correct statements as injecting insulin into the abdomen for faster absorption and rotating injection sites to prevent lipodystrophy are appropriate insulin administration techniques. Therefore, the client does not need further teaching on these aspects.
