Nursing Process Exam Questions

Correct Answer: D

Rationale: The correct answer is D because a low-carbohydrate, high-protein diet helps stabilize blood sugar levels and prevents hypoglycemic episodes. Carbohydrates cause rapid spikes and drops in blood sugar, while protein helps maintain stable levels. Avoiding fasting also helps regulate blood sugar. Choice A is incorrect as increasing saturated fat and fasting can worsen hypoglycemia. Choice B is incorrect as vitamins and iron do not directly address hypoglycemia. Choice C is incorrect as relying on sugary foods like candy bars can lead to further blood sugar imbalances.

Correct Answer: D

Rationale: The correct answer is D: Calcium. Calcium is necessary for the chemical clotting process because it plays a crucial role in the activation of various clotting factors, leading to the formation of a blood clot. Without sufficient calcium, the clotting cascade would not be able to proceed effectively. Iron (choice A) is essential for red blood cell production, not clotting. Potassium (choice B) and Sodium (choice C) are important for various physiological functions but are not directly involved in the clotting process.

Correct Answer: A

Rationale: The correct answer is A because gathering and organizing needed supplies is a crucial step before performing a complex dressing change. By ensuring all necessary supplies are readily available, the nurse can streamline the process, minimize interruptions, and promote efficiency. This step also helps maintain aseptic technique and prevent the spread of infection. Deciding on goals and outcomes (B) is important but typically done as part of the care planning process, not immediately before a dressing change. Assessing the patient's readiness (C) is also important but can be done concurrently with gathering supplies. Calling for assistance (D) may be necessary in some situations, but it is not the immediate step required just before changing the dressing.

Correct Answer: A

Rationale: The correct answer is A: Diagnosis. In this scenario, the nurse needs to analyze the data and identify the patient's problem, which is urinary retention due to abnormal kidney function and decreased oral intake. This step is crucial to develop a care plan. Planning (B) comes after diagnosis, where interventions are determined. Implementation (C) involves executing the care plan, and Evaluation (D) is the final step to assess the effectiveness of interventions.

Correct Answer: B

Rationale: The correct answer is B: Block beta stimulation in the heart. Propranolol is a beta-blocker that works by blocking the beta receptors in the heart, which reduces the heart's workload and oxygen demand, making it an effective treatment for angina. By blocking beta stimulation, propranolol helps to decrease heart rate, blood pressure, and myocardial contractility. This ultimately improves oxygen supply to the heart muscle. Explanation for other choices: A: Act as a vasoconstrictor - Propranolol does not act as a vasoconstrictor; it actually can cause vasodilation in some cases. C: Act as a vasodilator - Propranolol is not primarily a vasodilator; its main action is to block beta stimulation in the heart. D: Increase the heart rate - Propranolol actually decreases heart rate by blocking beta receptors in the heart.
