1. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What is a key contraindication that the nurse should review with the patient?
- A. History of hypertension
- B. Use of nitrates
- C. Use of antihypertensive medications
- D. History of peptic ulcer disease
Correct answer: B
Rationale: The correct answer is B: 'Use of nitrates.' Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both act as vasodilators, and their combined use can lead to a dangerous drop in blood pressure. Choices A, C, and D are incorrect because having a history of hypertension, using antihypertensive medications, or having a history of peptic ulcer disease are not key contraindications for sildenafil use.
2. The complexities of the current health care delivery systems require a variety of leadership styles. Which of the following leadership styles would be most effective in this environment?
- A. Autocratic leadership
- B. Laissez-faire leadership
- C. Transactional leadership
- D. Transformational leadership
Correct answer: D
Rationale: In complex health care environments, transformational leadership is the most effective style. This leadership approach focuses on inspiring and motivating staff towards a shared vision. Autocratic leadership (choice A) is too controlling and may not foster innovation and adaptability needed in complex systems. Laissez-faire leadership (choice B) lacks guidance and may lead to confusion in intricate healthcare settings. Transactional leadership (choice C) focuses on tasks and rewards, but may not be as effective in promoting innovation and change management required in complex health care delivery systems.
3. Which psychological perspective, emerging in the 1950s and 1960s, reflects a renewed interest in studying the mind or consciousness, similar to psychology's early days as a science in the late 1800s?
- A. Cognitive perspective.
- B. Mental perspective.
- C. Philosophical perspective.
- D. Biological perspective.
Correct answer: A
Rationale: The correct answer is the Cognitive perspective. The cognitive perspective indeed emerged in the 1950s and 1960s, reflecting a renewed interest in studying the mind and consciousness, akin to early psychology's focus when it first established as a science in the late 1800s. This perspective emphasizes mental processes, problem-solving, decision-making, and information processing. Choices B, C, and D are incorrect because the mental perspective is too generic and does not capture the emphasis on processes, the philosophical perspective is more focused on theories and concepts, and the biological perspective centers on the influence of biology on behavior rather than consciousness and mental processes.
4. A healthcare professional in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?
- A. Isosorbide
- B. Phenytoin
- C. Metronidazole
- D. Prednisone
Correct answer: A
Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.
5. The client is on digoxin and has severe digoxin toxicity. What is the nursing priority action?
- A. Check the potassium level.
- B. Give Digibind as an antidote.
- C. Change the dosing of digoxin to every other day.
- D. Administer a potassium supplement to decrease digoxin toxicity.
Correct answer: B
Rationale: The correct answer is to give Digibind as an antidote in cases of severe digoxin toxicity. Digibind works by binding to digoxin and preventing it from causing further harm. Checking the potassium level (choice A) is important but not the priority when the client has severe toxicity. Changing the dosing to every other day (choice C) is not appropriate in the setting of severe toxicity where immediate action is required. Giving a potassium supplement (choice D) may be needed eventually, but the priority is to administer Digibind to counteract the toxic effects of digoxin.
