Question 1 of 5
What is the primary action of digoxin when prescribed to a patient with heart failure?
Correct Answer: C
Rationale: The primary action of digoxin in heart failure is to strengthen cardiac contractions. Digoxin inhibits the sodium-potassium pump, leading to an increase in intracellular calcium levels, which enhances the force of myocardial contractions. This helps improve cardiac output and symptoms of heart failure.
Explanation:
A: Incorrect - Digoxin does not increase heart rate, it mainly affects the strength of contractions.
B: Incorrect - Digoxin does not decrease cardiac output; it actually helps improve it by enhancing contractility.
D: Incorrect - Digoxin may have a slight effect on lowering blood pressure, but its primary action in heart failure is to strengthen cardiac contractions, not lower blood pressure.
Question 2 of 5
The charge nurse observes that a client with a nasogastric tube on low intermittent suction is drinking a glass of water immediately after the unlicensed assistive personnel (UAP) left the room. What action should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Remove the glass of water and speak to the UAP. The rationale is as follows: 1) Drinking water with low intermittent suction can cause complications. 2) Immediate action is necessary to prevent harm. 3) Speaking to the UAP clarifies the situation and provides education. 4) Removing the glass of water ensures the client's safety.
Incorrect choices:
B: Discussing at the end of the day delays action and puts the client at risk.
C: Writing an incident report is important, but immediate intervention is needed first.
D: Reminding the client of electrolyte imbalance does not address the current issue of drinking water with a nasogastric tube.
Question 3 of 5
The healthcare provider formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely cause for this nursing diagnosis?
Correct Answer: B
Rationale: The correct answer is B: Diminished cough effort. In myasthenia gravis, muscle weakness can affect the muscles involved in coughing, leading to diminished cough effort. This can result in ineffective airway clearance, putting the client at high risk for respiratory complications. Pain during coughing (choice
A) may occur but is not the primary cause of ineffective airway clearance in myasthenia gravis. Thick, dry secretions (choice
C) and excessive inflammation (choice
D) may contribute to airway clearance issues but are not as directly related to the underlying muscle weakness seen in myasthenia gravis.
Question 4 of 5
A patient with type 2 diabetes is prescribed metformin. What instruction should the nurse provide regarding this medication?
Correct Answer: C
Rationale:
Step-by-step rationale for choice C:
1. Metformin can cause gastrointestinal side effects.
2. Taking it with meals helps reduce stomach upset.
3. It also helps in better absorption and effectiveness.
4.
Therefore, the nurse should instruct the patient to take metformin with meals.
Summary of other choices:
A: Taking on an empty stomach can worsen gastrointestinal side effects.
B: Metformin doesn't typically cause hypoglycemia.
D: Increasing simple carbohydrates can counteract the effects of metformin.
Question 5 of 5
A patient with glaucoma is prescribed timolol eye drops. What is the primary action of this medication?
Correct Answer: A
Rationale: The correct answer is A: Reduce intraocular pressure. Timolol is a beta-blocker that works by decreasing the production of aqueous humor in the eye, thereby reducing intraocular pressure. This action helps to prevent damage to the optic nerve in patients with glaucoma.
Choices B and C are incorrect because timolol does not affect pupil size.
Choice D is incorrect because timolol does not enhance tear production; in fact, it may have a drying effect on the eyes.
