Correct Answer: C

Rationale: The correct answer is C: Pink frothy sputum. This finding indicates pulmonary edema, which is characterized by fluid accumulation in the lungs. The pink color indicates the presence of blood in the sputum, a common sign of pulmonary edema. Excessive somnolence (
A) is more indicative of respiratory depression or hypoxia, while epistaxis (
B) is associated with hypertension or nasal trauma. Tachypnea (E) can be a sign of respiratory distress but does not specifically indicate pulmonary edema.

Correct Answer: A

Rationale: The correct answer is A: Maintain abduction of the affected extremity. After a total hip arthroplasty, maintaining abduction of the affected extremity helps prevent dislocation of the hip prosthesis. This position helps stabilize the hip joint and reduces the risk of complications. Option B (Position the client in high Fowler's position) is incorrect as it does not directly address the postoperative care specific to a total hip arthroplasty. Option C (Encourage the client to cross their legs at the ankles) is incorrect because crossing legs can create pressure on the hip joint and increase the risk of dislocation. Option D (Have the client bend forward at the waist while sitting) is incorrect as this could also increase the risk of hip dislocation.

Correct Answer: A

Rationale: The correct answer is A: Increase in blood pressure from 130/80 mm Hg to 180/100 mm Hg. Cushing's triad is a set of three classic signs indicating increased intracranial pressure (ICP). The triad includes hypertension (widening pulse pressure), bradycardia, and irregular respirations. In this case, an increase in blood pressure is consistent with the hypertension component of Cushing's triad. This occurs due to the body's compensatory mechanism to maintain perfusion to the brain in response to increased ICP.

Choices B, C, D, and E do not align with the classic signs of Cushing's triad. Bradycardia, not a decrease in heart rate, is typically seen in Cushing's triad. Rapid and shallow respirations are not part of the triad. Hypotension is not a characteristic finding in Cushing's triad.

Correct Answer: D

Rationale: The correct answer is D: Discard samples that contain urine. This is crucial because urine can interfere with the accuracy of the fecal occult blood test results, leading to false positives. By discarding samples that contain urine, the nurse ensures the reliability of the test.

A: Taking the sample from the outer edge of formed stool is not necessary for a guaiac smear sample.
B: Wearing sterile gloves is important for infection control but not specifically for collecting a guaiac smear sample.
C: Collecting three samples from a single bowel movement is not standard practice for fecal occult blood testing and may not be necessary.
E, F, G: No further options provided.

Correct Answer: A, B, D,E

Rationale: The correct actions for the nurse to take are A, B, D, and E. A - anticipating client prep for cardiac catheterization is important for timely intervention. B - assisting with a continuous heparin infusion helps prevent blood clot formation during the procedure. D - anticipating an increase in metoprolol dosage is necessary to manage cardiac workload during the procedure. E - obtaining a prescription for NPO status is crucial to prevent complications during the procedure.

Choices C (encouraging ambulation) and F (requesting an antibiotic prescription) are not directly related to preparing for cardiac catheterization and may not be necessary in this context.
