There are several factors that may cause a patient to present with sinus bradycardia. What are some causes of sinus bradycardia? (Select all that apply)

Beta blockers

Fever

Athletism

Sleeping

Answer and Explanation

Correct Answer : A,C,D

Choice A reason: Beta blockers are medications that can slow the heart rate, leading to sinus bradycardia. They are often prescribed for managing hypertension, arrhythmias, and other cardiovascular conditions. They work by blocking the effects of adrenaline on the heart, which reduces heart rate and blood pressure.

Choice B reason: Fever typically causes an increase in heart rate (tachycardia) rather than a decrease. The body's metabolic rate increases to fight infection, resulting in a higher heart rate.

Choice C reason: Athletism can result in sinus bradycardia because athletes often have a lower resting heart rate due to the increased efficiency of their cardiovascular system. Their hearts pump more effectively, requiring fewer beats per minute to circulate blood throughout the body.

Choice D reason: Sleeping naturally leads to a slower heart rate due to the relaxation of the body and reduced metabolic demands during rest. Sinus bradycardia during sleep is generally considered normal and not a cause for concern.

Correct Answer is B

Explanation

Choice A reason: Skipping a weight check post-dialysis is not recommended. Monitoring weight is crucial to assess fluid balance and effectiveness of dialysis.

Choice B reason: Warming the dialysate solution before instillation is important to prevent discomfort and cramping during the dialysis process. This ensures the solution is at body temperature.

Choice C reason: Packing the catheter exit site with gauze is not recommended. The site should be kept clean and dry, with proper sterile dressing.

Choice D reason: Avoiding foods high in potassium is more relevant for clients on hemodialysis rather than peritoneal dialysis. Clients on peritoneal dialysis have fewer dietary restrictions regarding potassium.

A. Symmetrical joint pain that is relieved with rest B. Unilateral pain in the weight-bearing joints C. Symmetrical joint pain D. Hypoglycemia

Correct Answer is C

Explanation

Choice A reason: Symmetrical joint pain that is relieved with rest is more characteristic of osteoarthritis, not rheumatoid arthritis. RA typically involves persistent, symmetrical joint pain and inflammation.

Choice B reason: Unilateral pain in the weight-bearing joints is not characteristic of RA. Rheumatoid arthritis generally affects joints symmetrically on both sides of the body.

Choice C reason: Symmetrical joint pain is a hallmark of rheumatoid arthritis. RA causes inflammation and pain in multiple joints, typically affecting the same joints on both sides of the body.

Choice D reason: Hypoglycemia is not related to rheumatoid arthritis. RA primarily involves joint inflammation and systemic symptoms like fatigue and fever but does not directly impact blood sugar levels.
