Correct Answer: A

Rationale: Before an MRI scan with contrast, the nurse should assess if the client has any metal implants. Metal implants can interfere with the magnetic field of the MRI, which can pose a risk to the client's safety and compromise the quality of the scan. Assessing for allergies to iodine or shellfish (
Choice
B) is important for contrast agents but not specific to metal implants. Claustrophobia assessment (
Choice
C) is relevant for MRI scans due to the confined space but not specific to metal implants. Past procedures (
Choice
D) are important for comparison but not directly related to the risks associated with metal implants during an MRI scan with contrast.

Correct Answer: D

Rationale: The most important instruction the nurse should provide to a client prescribed alendronate (Fosamax) for osteoporosis is to take the medication with a full glass of water. This is crucial to help prevent esophageal irritation. Option A is correct as alendronate should be taken in the morning on an empty stomach. Option C is incorrect because the client should remain upright for at least 30 minutes after taking the medication, not lie down. Option B is incorrect and a duplicate of Option A.

Correct Answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy.

Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

Correct Answer: D

Rationale: After sustaining burns to the face and neck, positioning is crucial to maintain functional posture, reduce pain, and prevent contractures. Placing the neck forward using pillows under the head and sandbags on both sides is the best option in this scenario. This position helps prevent neck and facial contractures, allowing for optimal function and healing.

Choices A, B, and C do not adequately address the specific needs of a client with burns to the face and neck.
Choice A could potentially exacerbate neck contractures,
Choice B focuses on arm support rather than neck and face positioning, and
Choice C does not directly address the needs of the burned face and neck, making them less effective in preventing contractures in these critical areas.

Correct Answer: D

Rationale: When managing hypertension, it is crucial to adopt comprehensive dietary changes. This includes reducing sodium intake to help lower blood pressure, increasing potassium intake to counteract the effects of sodium and help regulate blood pressure, and limiting alcohol consumption as excessive alcohol can raise blood pressure.
Therefore, emphasizing all the options provided (A, B, and
C) is essential in effectively managing hypertension and reducing overall cardiovascular risk.

Choices A, B, and C are not individually sufficient as a single dietary modification but collectively work together to support blood pressure management.
