Correct Answer: A

Rationale: The correct answer is A: 'Do you smoke cigarettes?' Smoking is a major risk factor for bladder cancer. Cigarette smoke contains harmful chemicals that can accumulate in the urine and damage the lining of the bladder, increasing the risk of developing cancer. Alcohol use, recreational drug use, and most prescription drugs are not directly linked to an increased risk of bladder cancer. It is important for the nurse to assess smoking history as a significant risk factor in determining the client's risk for bladder cancer.

Correct Answer: C

Rationale: The correct answer is C. The presence of ketones in the urine is abnormal. Ketones in the urine may indicate a state of ketosis, which is commonly seen in uncontrolled diabetes, fasting, or a low-carbohydrate diet. A normal pH range of urine is 4.5 to 7.8, making a pH of 6.0 within the normal range. An absence of protein is a normal finding in urine, as proteinuria (presence of protein) is abnormal. A specific gravity of 1.018 falls within the normal range of 1.016 to 1.022. Therefore, the presence of ketones is the abnormal finding in this scenario.

Correct Answer: C

Rationale: After a nephrostomy, the nurse should assess the client for complications and urgently notify the provider if there is foul-smelling drainage, bloody drainage at the site, or both. Foul-smelling drainage can indicate infection, while bloody drainage may suggest bleeding. Clear drainage is generally normal after a nephrostomy. A headache would not typically be directly related to nephrostomy complications. Therefore, options A and B are correct choices for urgent notification, making option C the correct answer.

Correct Answer: A

Rationale: The correct action for the nurse to take when the client has a urine osmolality of 1200 mOsm/L, indicating dehydration, is to encourage the client to drink more fluids. Dehydration can lead to elevated urine osmolality, and increasing fluid intake can help rehydrate the client. A low-sodium diet is not the priority in this scenario as it would not directly address the dehydration indicated by the high urine osmolality. Administering an intravenous diuretic would further concentrate the urine, exacerbating the dehydration. Obtaining a suction device and implementing seizure precautions are not indicated based on the client's urine osmolality results and would not address the underlying issue of dehydration.

Correct Answer: B

Rationale: When a patient reports a previous rash with amoxicillin, which is a type of penicillin, there is a concern for a penicillin allergy. In such cases, using an alternative antibiotic like erythromycin, which is not a penicillin, is the appropriate approach to avoid potential cross-reactivity and allergic reactions. Giving smaller doses of penicillin does not address the underlying allergy issue and can still lead to severe hypersensitivity reactions. Diphenhydramine (Benadryl) is used to manage allergic reactions but should not be the first choice in changing the antibiotic. While some patients allergic to penicillins may also be allergic to cephalosporins like cefuroxime, it is not the best immediate alternative in this scenario.
