Correct Answer: D

Rationale: The correct answer is D: Restricting fluids. In SIADH, there is an excess of antidiuretic hormone leading to water retention and dilutional hyponatremia. Restricting fluids helps to prevent further water retention and hyponatremia. Rapid IV fluid infusion (A) worsens the condition by further diluting sodium levels. Administering glucose-containing IV (B) is not directly related to treating SIADH. Encouraging increased oral intake (C) can exacerbate the condition by increasing fluid intake.

Correct Answer: D

Rationale: The correct answer is D because a class V finding on a Pap test indicates severe dysplasia or carcinoma in situ, which requires further evaluation through a biopsy to confirm the presence of abnormal cells. This finding is not normal and necessitates immediate action for diagnosis and potential treatment. Choices A, B, and C are incorrect because they do not address the urgency and seriousness of a class V finding, which mandates prompt follow-up to rule out or confirm the presence of precancerous or cancerous cells.

Correct Answer: A

Rationale: The correct answer is A because asthma is characterized by inflammation and bronchoconstriction of the airways, leading to difficulty breathing. This explanation accurately describes the pathophysiology of asthma. Explanation for other choices: B: Fluid in the lungs is more indicative of conditions like pneumonia or pulmonary edema, not asthma. C: Asthma involves airway constriction and inflammation, not stretching and non-functionality. D: Asthma is not caused by infection but rather triggered by factors like allergens or irritants.

Correct Answer: C

Rationale: The correct answer is C: Uterine body. The rationale is that the most common site of cancer for females is uterine body, specifically endometrial cancer. This is due to the high prevalence of hormonal imbalances and estrogen exposure, which are risk factors for this type of cancer. The other choices, A: Uterine cervix, B: Vagina, and D: Fallopian tube, are less common sites of cancer in females compared to the uterine body. Understanding the prevalence and risk factors associated with each site of cancer is crucial for nurses to educate clients effectively.

Correct Answer: C

Rationale: The correct answer is C because flushing the central venous catheter with a heparinized solution before blood withdrawal is essential to maintain catheter patency and prevent clot formation. This step ensures the catheter is clear of any blockages, allowing for accurate blood sampling. Choice A is incorrect because assembling supplies should come after preparing the catheter. Choice B is incorrect as discarding blood before flushing the catheter may lead to inaccurate test results. Choice D is incorrect as replacing the catheter cap without flushing may lead to clot formation and catheter malfunction.
