A nurse is reinforcing teaching about the side effects of metoprolol. Which of the following client statements indicates an understanding of the teaching?
"I need to be careful when standing up from bed."
"I should limit my intake of leafy green vegetables."
"I should expect some weight loss."
"I may experience loss of taste."
The Correct Answer is A
Choice A reason: Metoprolol, a beta-blocker, lowers BP, causing orthostatic hypotension. Caution when standing prevents falls, showing grasp of this key side effect.
Choice B reason: Leafy greens affect warfarin, not metoprolol. No dietary restriction applies, so this reflects confusion about beta-blocker side effects.
Choice C reason: Weight gain, not loss, may occur with metoprolol from fluid retention. Expecting loss misinterprets its metabolic impact, indicating misunderstanding.
Choice D reason: Taste loss isn’t a metoprolol effect; it’s linked to other drugs. This shows incorrect attribution of side effects to the medication.

Correct Answer is B
Explanation
Choice A reason: Calcium-fortified juice binds doxycycline, reducing absorption via chelation in the gut. Scientifically, tetracyclines like doxycycline lose efficacy with divalent cations, worsening nausea without treating chlamydia, making this counterproductive to therapeutic goals and pharmacokinetics.
Choice B reason: Taking doxycycline with crackers minimizes gastric irritation, reducing nausea while maintaining absorption. Scientifically, light food buffers the stomach without significantly impairing tetracycline bioavailability, aligning with evidence-based advice to improve tolerability and adherence in chlamydia treatment.
Choice C reason: Lying down after doxycycline risks esophageal irritation or reflux, worsening nausea. Scientifically, upright posture post-dose prevents drug stasis, which can cause ulcers, making this contrary to safe administration practices for tetracyclines per clinical guidelines.
Choice D reason: Antacids with magnesium or aluminum bind doxycycline, decreasing absorption and efficacy. Scientifically, this interaction undermines chlamydia treatment, as tetracyclines require an acidic environment for uptake, rendering this incompatible with therapeutic success and worsening outcomes.
Correct Answer is D
Explanation
Choice A reason: Meningococcal vaccine starts at 11-12 years, not infancy; three doses by kindergarten is incorrect. Scientifically, this misaligns with CDC schedules, as 2-month-olds get other vaccines (e.g., DTaP), showing misunderstanding of immunization timing.
Choice B reason: No feeding restriction exists for immunizations; fasting isn’t required. Scientifically, nutrition supports immune response, and this contradicts standard practice, as feeding doesn’t affect vaccine efficacy or safety, indicating a preparation misconception.
Choice C reason: High fever for 24 hours isn’t typical; mild fever may occur but not guaranteed. Scientifically, this exaggerates normal vaccine reactions (e.g., low-grade fever), misrepresenting expected immune responses, suggesting inaccurate outcome expectations.
Choice D reason: Rotavirus vaccine is oral at 2 months, per CDC schedule, aligning with its live attenuated form. Scientifically, this reflects correct administration knowledge, as it targets gut immunity, showing the guardian understands this immunization’s delivery accurately.
