Correct Answer: C

Rationale: The correct answer is C: Airway obstruction. Postoperatively, a nurse must assess for airway patency in a client with a nasal fracture to ensure proper breathing. Any swelling or bleeding in the nasal area can lead to airway obstruction, which is a critical concern that needs immediate intervention. Choices A, B, and D are incorrect because an allergic reaction, extreme sense of smell, and stridor are not typically associated with postoperative assessment of a nasal fracture. It is crucial to prioritize airway assessment to prevent any complications related to breathing difficulties in this situation.

Correct Answer: B

Rationale: Step 1: Antibiotics are prescribed to treat urethritis, indicating a bacterial infection in the urinary tract. Step 2: Increasing water intake (2-3 L daily) promotes renal blood flow, dilutes urine, and helps flush out bacteria from the urinary tract, aiding in the elimination of infection. Step 3: Adequate hydration helps prevent the formation of concentrated urine, reducing the risk of recurrent urinary tract infections. Step 4: Therefore, choice B is correct as it directly addresses the underlying cause of the client's symptoms. Summary: Choices A, C, and D are incorrect as they do not directly target the bacterial infection causing the urinary discomfort. Drinking water will not specifically help with incontinence, eliminate odors, or provide pain relief.

Correct Answer: A

Rationale: The correct answer is A: Detects the presence of malignant cells. Biopsy involves taking a sample of tissue to examine under a microscope for the presence of abnormal or cancerous cells. This procedure is crucial for diagnosing cancer accurately. Choice B (Measures hemoglobin content) is incorrect because hemoglobin content is typically measured through blood tests, not biopsies. Choice C (Measures the RBC size) is incorrect as RBC size is usually assessed through a complete blood count (CBC) test, not a biopsy. Choice D (Detects arterial occlusion) is incorrect because arterial occlusion is typically diagnosed through imaging studies like Doppler ultrasound or angiography, not through a biopsy procedure.

Correct Answer: A

Rationale: The correct answer is A: status of client’s tetanus immunization. It is critical because an open fracture poses a risk of infection, and tetanus prophylaxis is necessary to prevent tetanus infection. Tetanus is caused by a bacterium commonly found in soil and can enter the body through open wounds. Assessing the client's tetanus immunization status helps determine the need for a tetanus booster to prevent potential complications. Incorrect choices: B: Current blood alcohol level - While relevant to the situation, the priority in this case is preventing infection from the open fracture. C: Support systems available at home to assist with care - Important for discharge planning but not the immediate priority. D: Last time client voided - Not critical in this scenario compared to preventing infection from the open fracture.

Correct Answer: B

Rationale: The correct answer is B because monitoring the site and progress of the infusion every hour is crucial to prevent complications like infiltration or infection in clients with hypertension. Choice A is incorrect as checking BP every hour is excessive. Choice C is incorrect as daily monitoring may not detect issues promptly. Choice D is incorrect as pulse rate monitoring is not directly related to IV fluid administration in this context. Monitoring the site and progress hourly ensures timely intervention if any issues arise.
