Correct Answer: B

Rationale: Late decelerations indicate uteroplacental insufficiency, and the priority nursing action is to improve placental perfusion. Positioning the client on their side, particularly the left side, can enhance blood flow to the placenta and fetus by reducing pressure on the vena cava and increasing cardiac output. Applying oxygen, although helpful, is not the initial priority in this situation. Calling for a Cesarean delivery is not warranted unless other interventions fail to correct the late decelerations. Administering oxytocin can worsen the condition by increasing uterine contractions, exacerbating fetal distress.

Correct Answer: A

Rationale: Correct answer: To assess a patient with potential diabetic ketoacidosis (DKA), healthcare providers should monitor blood glucose and check for ketones in the urine. Elevated blood glucose levels and the presence of ketones in urine are indicative of DKA. Choice B is incorrect because administering insulin and providing fluids are treatments for DKA rather than assessment measures. Choice C is incorrect as administering potassium and checking for electrolyte imbalance are interventions related to managing DKA complications, not initial assessment. Choice D is incorrect because administering sodium bicarbonate and monitoring urine output are not primary assessment actions for DKA.

Correct Answer: A

Rationale: Emptying the colostomy bag regularly is essential to prevent leakage and infection. By regularly emptying the bag, the risk of irritation to the skin surrounding the stoma is reduced. Providing a high-fiber diet is important for overall bowel health but is not directly related to colostomy care. While monitoring for signs of infection is crucial, the primary focus should be on proper bag emptying. Changing the colostomy bag every 3 days may not be necessary for all patients and could vary based on individual needs and the type of colostomy.

Correct Answer: D

Rationale: When a patient is receiving IV potassium, it is crucial to monitor various parameters to ensure patient safety. Monitoring the ECG helps in identifying any potential dysrhythmias that may occur due to potassium imbalances. Monitoring urine output is important as potassium levels can affect renal function. Monitoring serum potassium levels is essential to assess the effectiveness of the IV potassium therapy. Therefore, all the options - monitoring ECG for dysrhythmias, urine output, and serum potassium levels - are necessary when administering IV potassium, making 'All of the above' the correct answer. Choices A, B, and C are not individually sufficient as they each address different aspects of patient monitoring when receiving IV potassium.

Correct Answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.
