A nurse is caring for a client who has a history of hypertension. Which of the following findings should the nurse recognize is indicative of transient ischemic attacks?

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.

Choice A reason: Using a trapeze builds upper body strength, aiding transfers and mobility post-amputation. Scientifically, this promotes independence by enhancing muscle power for prosthetic use, aligning with rehabilitation goals to restore function and reduce reliance on others early in recovery.

Choice B reason: Abduction with a pillow prevents adduction contractures but doesn’t directly enhance mobility. It’s passive, not active, support. Scientifically, while useful, it lacks the progressive impact of strength training, making it secondary to fostering independence in amputation care.

Choice C reason: Avoiding prone position is outdated; prone lying prevents hip flexion contractures, aiding mobility. Scientifically, this caution hinders rehabilitation, as stretching the hip flexors supports prosthetic alignment and walking, contradicting progression toward independence.

Choice D reason: Loose dressings don’t promote mobility; tight, controlled dressings reduce edema for prosthetic fitting. Scientifically, this delays healing and strength-building, as proper wound management, not loose coverage, supports physical progression in amputation recovery.
