Correct Answer: C

Rationale: The correct answer is C: Psychomotor. The nurse is demonstrating psychomotor skills by inserting an IV catheter correctly. Psychomotor skills involve the ability to perform physical tasks effectively and efficiently. This skill requires coordination, dexterity, and precision. The other choices are incorrect because: A: Cognitive skills involve thinking, analyzing, and problem-solving. B: Interpersonal skills involve communication and interaction with others. D: Judgmental skills involve critical thinking and decision-making.

Correct Answer: C

Rationale: The correct answer is C: Pulmonary artery obstructive pressure (PACP). The multilumen pulmonary artery catheter measures hemodynamic pressures in the heart. When the catheter tip enters small branches of the pulmonary artery, it can assess Central Venous Pressure (A), Pulmonary Artery Capillary Pressure (B), and Pulmonary Artery Wedge Pressure (D). Pulmonary artery obstructive pressure is not a standard hemodynamic measurement and is not assessed using this catheter. It is crucial to differentiate between the various pressures measured to accurately assess the patient's cardiac status.

Correct Answer: C

Rationale: Step 1: The nurse should explain that bladder irrigation is necessary to prevent blood clots from occluding the catheter after a TURP procedure. Step 2: Without irrigation, blood clots could block the catheter, leading to urinary retention and potential complications. Step 3: This explanation addresses the patient's concern about increased pain and highlights the importance of the irrigation in maintaining proper urine flow. Step 4: Choice A is incorrect because the primary purpose of irrigation is not to stop bleeding but to prevent clot formation. Choice B is incorrect because the irrigation is not for administering antibiotics. Choice D is incorrect as it does not address the issue of clot formation.

Correct Answer: D

Rationale: The correct answer is D. Epinephrine, when applied locally, constricts blood vessels, reducing blood flow and slowing down bleeding. This vasoconstrictive effect helps control nosebleeds effectively. Choice A is incorrect because although epinephrine can raise blood pressure, it is not the primary mechanism for treating nosebleeds. Choice B is incorrect as epinephrine's bronchodilation effect is not relevant in this context. Choice C is incorrect as while promoting blood clotting is beneficial, epinephrine primarily acts by vasoconstriction to control bleeding.

Correct Answer: C

Rationale: The correct answer is C: Use the smallest needle possible for injections. This is important for a client with thrombocytopenia because they have a low platelet count, leading to an increased risk of bleeding. Using a small needle minimizes the risk of causing bleeding or bruising during injections. Limiting family visits (choice A) is not directly related to protecting the client from bleeding. Encouraging wheelchair use (choice B) is not specifically relevant to protecting the client with thrombocytopenia. Maintaining accurate fluid intake and output records (choice D) is important but not directly related to preventing bleeding in a client with thrombocytopenia.
