Correct Answer: C

Rationale: Keeping the client's neck in a midline position is essential when caring for a client with increased intracranial pressure (ICP) as it helps promote optimal blood flow and reduces the risk of further increasing ICP. Placing pillows behind the client's head (Choice A) may not be recommended as it could potentially increase ICP. Putting the client in a Sims' position (Choice B) and maintaining hip flexion at a 90° angle (Choice D) are not directly related to managing increased ICP and are not the priority interventions in this situation.

Correct Answer: D

Rationale: The correct answer is D. The nurse should instruct the client to avoid corticosteroids and vitamin C prior to testing to prevent false-positive results. Choice A is incorrect because stool samples from bowel movements, not from digital rectal examinations, are used for FOBT. Choice B is incorrect because a stimulant laxative is not typically prescribed before FOBT; rather, the client is instructed to follow specific dietary restrictions. Choice C is incorrect because biennial fecal occult blood testing for colorectal cancer screening usually begins at 50 years old, not 40.

Correct Answer: A

Rationale: A sodium level of 122 mEq/L indicates hyponatremia, which is characterized by decreased deep tendon reflexes. Hyponatremia leads to neurological symptoms such as altered reflexes. Choices B, C, and D are not typically associated with hyponatremia. Positive Trousseau's sign is related to hypocalcemia, hypoactive bowel sounds can be seen in paralytic ileus or decreased peristalsis, and sticky mucous membranes are not specific findings related to sodium imbalances.

Correct Answer: A

Rationale: The correct answer is A. The nurse should report these vital signs to the provider immediately as they indicate increased temperature, tachycardia, and tachypnea, which are signs of possible infection or systemic inflammatory response. This could exacerbate the client's unstable angina and needs prompt evaluation. Choices B, C, and D are not as urgent as the vital signs in option A and do not directly indicate a worsening condition in the context of unstable angina.

Correct Answer: D

Rationale: The correct answer is D. Limiting activities that require bending at the waist can help prevent episodes of reflux in clients with GERD. Choices A, B, and C are incorrect. Taking medicine with orange juice may not be appropriate as citrus juices can aggravate GERD. Having a bedtime snack can exacerbate heartburn by increasing stomach acid production, and lying down after meals can worsen symptoms of GERD by allowing stomach acid to flow back into the esophagus.
