Question 1 of 5
Below question: don't know the correct combination. Below is what was picked but incorrect. The NP explains to the NP students about penicillin. Which is true about penicillin? Select all that apply
Correct Answer: B,C
Rationale: Answer B is correct because penicillin is indeed a beta-lactam antibiotic, which refers to its chemical structure. Answer C is correct because penicillin primarily targets actively growing and dividing bacteria. Answer A is incorrect because penicillin works by inhibiting bacterial cell wall synthesis, not by causing bacteria to take up excess water and rupture. Answer D is incorrect because penicillin is bactericidal, meaning it kills bacteria, as opposed to being bacteriostatic, which inhibits bacterial growth.
Question 2 of 5
Which patient statement suggests to the provider that the patient's nonadherence with their medication plan is related to dissatisfaction with the therapy?
Correct Answer: D
Rationale: The correct answer is D because the patient's statement indicates dissatisfaction with the therapy. The patient expected more weight loss after taking the medication for over a week, suggesting they are not happy with the results. This dissatisfaction may lead to nonadherence. A: Financial issues are a common reason for nonadherence, not necessarily linked to dissatisfaction with therapy. B: Time constraints can also impact adherence but do not directly indicate dissatisfaction with therapy. C: Forgetfulness is a common reason for nonadherence and does not necessarily imply dissatisfaction with therapy.
Question 3 of 5
The recommended range for maintaining serum theophylline levels is:
Correct Answer: D
Rationale: The correct answer is D (10 to 20 ug/ml) for maintaining serum theophylline levels. This range is recommended for therapeutic efficacy with minimal side effects. Levels below 10 ug/ml may not be effective, while levels above 20 ug/ml can lead to toxicity. Choice A (20 to 25 ug/ml) and Choice B (30 to 40 ug/ml) are too high and could result in toxicity. Choice C (0.05 to 2 ug/ml) is too low for therapeutic effect. Therefore, maintaining theophylline levels within the range of 10 to 20 ug/ml is the ideal balance for effective treatment.
Question 4 of 5
A patient is taking Loracaserin (Belviq) for weight-loss. Which supplement taken by this patient would cause you to be alarmed?
Correct Answer: C
Rationale: The correct answer is C: St. John's wort. St. John's wort is known to interact with many medications, including Loracaserin. It can decrease the effectiveness of Loracaserin, leading to reduced weight-loss benefits. Garlic (A), Ginseng (B), and Ginkgo biloba (D) do not have significant interactions with Loracaserin. Always consult a healthcare provider before taking any new supplements to prevent potential adverse effects.
Question 5 of 5
The reason that two MMR vaccines at least a month apart are recommended is:
Correct Answer: A
Rationale: Step 1: The correct answer is A because it states that only 95% of patients are fully immunized for measles after the first vaccine, with 99% having immunity after two doses of MMR. Step 2: This indicates that a single dose may not provide full immunity, necessitating a second dose. Step 3: By providing two doses, the likelihood of achieving immunity in a higher percentage of patients increases. Step 4: This ensures a more thorough and effective immunization process. Summary: Choice A is correct because it emphasizes the importance of two doses for higher immunity rates. Choices B, C, and D are incorrect as they do not directly address the specific need for two MMR doses for optimal immunization effectiveness.
