Nursing Process Exam Questions

Correct Answer: C

Rationale: Rationale: - Paraplegia refers to paralysis of the lower extremities. - The prefix "para-" means alongside or beside, indicating lower body involvement. - Option A is incorrect as it refers to quadriplegia. - Option B is incorrect as it refers to quadriplegia. - Option D is incorrect as it refers to hemiplegia.

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.

Correct Answer: D

Rationale: The correct answer is D because a respiratory rate of 8 breaths/min indicates respiratory depression, a serious adverse effect of morphine. Morphine is a central nervous system depressant that can suppress the respiratory drive, leading to hypoventilation and potentially respiratory failure. This is a life-threatening complication that requires immediate intervention. A: Voiding of 350mL of concentrated urine is not typically associated with morphine use. B: An irregular heart rate of 82 beats/min is within a normal range and not a common adverse effect of morphine. C: Pupils constricted and equal is a common side effect of morphine due to its action on the central nervous system, not necessarily indicating an adverse effect.

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 hypertension is primarily determined by peripheral vascular resistance, which refers to the resistance in the blood vessels that the heart must overcome to pump blood effectively. This is a key factor in the development of high blood pressure. Choice A is incorrect as it simplifies the concept to just the pumping action of the heart. Choice B is incorrect because hypertension is not just about having high readings on separate occasions but rather a sustained elevation in blood pressure. Choice C is incorrect as stress, activity, and emotions can influence blood pressure but are not the sole determinants of hypertension.
