1. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?
- A. Angiotensin I
- B. Angiotensin II
- C. Angiotensin III
- D. Renin
Correct answer: B
Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.
2. The healthcare provider is providing care to a child who was treated with aspirin during a viral infection. Which clinical manifestations should cause the healthcare provider concern?
- A. Nausea, vomiting, and confusion
- B. Headache, vomiting, and seizures
- C. Sore throat, moist respirations, and cough
- D. Fever, rash, and photophobia
Correct answer: A
Rationale: The symptoms of nausea, vomiting, and confusion are concerning as they are indicative of Reye's syndrome, a rare but serious condition associated with aspirin use in children during viral illnesses. Reye's syndrome can lead to severe complications, including brain and liver damage, hence prompt recognition and management are crucial.
3. Which stage of motor learning is illustrated as the toddler attempts to place a shape into a container multiple times using an effective reach and grasp pattern often but makes errors?
- A. Skill Acquisition
- B. Perceptual Learning
- C. Functional Performance
- D. Exploratory Activity
Correct answer: B
Rationale: The correct answer is Perceptual Learning. In this stage, the toddler learns from sensory input and refines their movements over time, even though errors may still occur. This process involves improving coordination and fine-tuning motor skills based on feedback from repeated attempts.
4. A nurse assesses a male patient who has developed gynecomastia while receiving treatment for peptic ulcers. Which medication from the patient�s history should the nurse recognize as a contributing factor?
- A. Amoxicillin (Amoxil)
- B. Cimetidine (Tagamet)
- C. Metronidazole (Flagyl)
- D. Omeprazole (Prilosec)
Correct answer: B
Rationale: Cimetidine binds to androgen receptors, producing receptor blockade, which can cause enlarged breast tissue, reduced libido, and impotence. All these effects reverse when dosing stops. Amoxicillin, metronidazole, and omeprazole are not associated with gynecomastia.
5. A patient who has PUD and is receiving magnesium hydroxide (MOM) is experiencing an increased number of BM. Which is the nurse�s priority action?
- A. Ask the HCP for a reduction in dose
- B. Encourage the patient to increase dietary fiber
- C. Administer the drug with an aluminum hydroxide antacid
- D. Instruct patient to keep an accurate stool count
Correct answer: C
Rationale: MOM is a rapid-acting antacid with a prominent adverse effect of diarrhea. To compensate, it usually is administered in combo with aluminum hydroxide which promotes constipation. A reduction in dose might be necessary if the diarrhea is severe, but this is not a priority action. Increasing dietary fiber and keeping a stool count are appropriate actions to implement after adding an antacid to counteract the diarrhea effect.
