ATI Pathophysiology Final Exam

1. A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What condition would contraindicate the use of this medication?

Correct answer: B

Rationale: The correct answer is B: 'Use of nitrates.' Tadalafil (Cialis) is contraindicated in patients using nitrates due to the risk of severe hypotension. Nitrates and tadalafil both cause vasodilation, leading to a synergistic effect that can result in a dangerous drop in blood pressure. Choices A, C, and D are incorrect because a history of hypertension, the use of antihypertensive medications, and a history of peptic ulcer disease are not direct contraindications for tadalafil use.

2. A nurse practitioner is seeing a client in the clinic with a suspected diagnosis of bacterial meningitis. What should the nurse anticipate as the priority action?

Correct answer: A

Rationale: The correct answer is to administer the first dose of antibiotics immediately after blood cultures are drawn for suspected bacterial meningitis. This is crucial to initiate treatment promptly and improve patient outcomes. Starting an IV line and administering corticosteroids (Choice B) may be part of the treatment plan but administering antibiotics is the priority. Isolating the client (Choice C) is important to prevent the spread of infection but not the priority over initiating antibiotic therapy. Performing a lumbar puncture (Choice D) may confirm the diagnosis, but treatment should not be delayed for this step in suspected cases of bacterial meningitis.

3. Why is a beta-blocker prescribed to a client with a history of myocardial infarction?

Correct answer: A

Rationale: The primary reason for administering a beta-blocker to a client with a history of myocardial infarction is to reduce myocardial oxygen demand. By reducing myocardial oxygen demand, beta-blockers help decrease the workload on the heart, making it easier for the heart to function effectively. This is crucial for clients with a history of myocardial infarction to prevent further damage to the heart. Choice B is incorrect because beta-blockers do not aim to increase cardiac output; instead, they help improve cardiac function by reducing workload. Choice C is incorrect because while beta-blockers can help prevent certain arrhythmias, the primary reason for their use in this case is to reduce myocardial oxygen demand. Choice D is incorrect as preventing angina is not the primary purpose of administering beta-blockers to a client with a history of myocardial infarction.

4. A patient is starting on medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse include in the patient teaching?

Correct answer: B

Rationale: The correct answer is B. Patients starting on medroxyprogesterone acetate (Provera) for endometriosis should be instructed to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Choice A is incorrect because medroxyprogesterone acetate can be taken with or without food. Choice C is unrelated to the medication and not a specific concern with its use. Choice D is incorrect as patients should not discontinue the medication without consulting their healthcare provider, even if side effects occur.

5. A 45-year-old diabetic male is experiencing erectile dysfunction. If his erectile dysfunction is caused by the nervous system, then the nurse can educate the client that the venous blood supply to the penis is controlled by:

Correct answer: B

Rationale: Erectile function is primarily controlled by the parasympathetic nervous system, which facilitates the dilation of blood vessels in the penis. The parasympathetic nerves are responsible for vasodilation in the penis, allowing blood to enter and creating an erection. Sympathetic nerves, on the other hand, are responsible for ejaculation by causing contraction of the muscles around the vas deferens. Somatic nerves are involved in sensation and movement, not specifically in controlling blood supply to the penis. Spinal reflexes can play a role in the erectile process, but they are not directly responsible for controlling the venous blood supply.
