Correct Answer: C

Rationale: The correct answer is C: Painful and frequent urination. Cloudy penile discharge is a common symptom of urethritis, which is inflammation of the urethra. Painful and frequent urination are classic symptoms of urethritis due to irritation and inflammation of the urinary tract. Throat or rectal infection (choice A) are not typically associated with urethritis. Chancres or vesicles on the genitals (choice B) are more indicative of sexually transmitted infections like syphilis or herpes. Oliguria and flank pain (choice D) are more suggestive of kidney or urinary tract issues rather than urethritis.

Correct Answer: C

Rationale: Step 1: Reading labels carefully on vials containing flush solutions for locks is crucial to ensure the correct solution is being used. Step 2: Potassium chloride should not be used to flush locks as it can be fatal if administered incorrectly. Step 3: By carefully reading labels, the nurse can verify that the correct solution is being used, thus minimizing the risk of using potassium chloride. Summary: - Choice A is incorrect as using a dilute form of potassium chloride does not address the issue of incorrect administration. - Choice B is incorrect as warming the solution does not prevent the risk associated with using potassium chloride. - Choice D is incorrect as replacing locks does not address the root cause of the issue, which is improper administration.

Correct Answer: C

Rationale: The correct answer is C: Hypercalcemia. In bone cancer, there can be excessive release of calcium from the bones, leading to elevated blood calcium levels. This can result in various complications such as kidney stones, cardiac arrhythmias, and weakness. Hyperkalemia (choice A) is not commonly associated with bone cancer. Hyponatremia (choice B) is more commonly seen in conditions like heart failure or kidney disease. Hypomagnesemia (choice D) is not a common electrolyte disturbance in bone cancer.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Acute bronchitis is characterized by inflammation of the bronchial tubes. 2. An initial sign of acute bronchitis is a nonproductive cough due to irritation of the bronchial tubes. 3. Anorexia and labored breathing may occur later as the condition progresses. 4. Gastric ulceration is not typically associated with acute bronchitis. Therefore, choice A (Nonproductive cough) is the correct answer as it aligns with the characteristic symptom of acute bronchitis, while the other choices are not typically observed in the initial stages of the condition.

Correct Answer: B

Rationale: The correct answer is B: Have a mammogram annually. Mammograms are recommended by the American Cancer Society for breast cancer screening in women as they are effective in detecting early signs of breast cancer. Mammograms have been shown to reduce mortality rates from breast cancer. Annual mammograms are crucial for early detection and treatment. A: Performing breast self-examination annually is not recommended as a standalone screening method as it has not been shown to significantly reduce mortality rates. C: Having a normal receptor assay annually is not a standard screening test for breast cancer recommended by the American Cancer Society. D: Having a physician conduct a clinical examination every 2 years is not as effective as annual mammograms for detecting early signs of breast cancer.
