The nurse is caring for a client with a heart rate of 48. His blood pressure is 120/80. Which finding will help the nurse determine the cause of the client's bradycardia?

The client has a fever.

The client has possible hemorrhage or bleeding.

The client has chronic obstructive pulmonary disease (COPD).

The client has calcium channel blocker medicate prescribed.

Answer and Explanation

The Correct Answer is D

A.   Fever can cause tachycardia (increased heart rate) rather than bradycardia. It is not typically associated with slowing of the heart rate unless there are other complicating factors such as severe infection or medication side effects.
B.   Significant blood loss can lead to hypovolemia (low blood volume), which can result in bradycardia as a compensatory mechanism to maintain blood pressure. However, the blood pressure in this scenario is

normal (120/80), which makes severe hemorrhage less likely unless compensated by fluid resuscitation or other factors.
C.   COPD can cause chronic hypoxia and respiratory acidosis, which can lead to chronic respiratory compensation and potentially bradycardia. However, COPD alone is less likely to cause bradycardia in the absence of severe exacerbation or other complicating factors.
D.   Calcium channel blockers (CCBs) are medications commonly prescribed for conditions such as hypertension, angina, and arrhythmias. They work by blocking calcium channels in cardiac and smooth muscle cells, resulting in decreased heart rate and vasodilation. Bradycardia is a known side effect of CCBs, especially when taken in excess or in combination with other medications that affect heart rate.

Correct Answer is ["A","B","C","E"]

Explanation

A. Postoperative patients often experience muscle tension and discomfort due to lying in one position for an extended period. A gentle back massage can help relieve muscle stiffness, promote relaxation, and improve circulation. It is a non-invasive comfort measure that can enhance the client's overall well- being.
B. Teaching relaxation techniques such as deep breathing exercises, guided imagery, or progressive muscle relaxation can help the client manage pain, reduce anxiety, and promote faster recovery. These techniques are beneficial postoperatively as they encourage relaxation and improve overall comfort.
C. Postoperative clients are at risk of developing respiratory complications such as atelectasis (partial lung collapse) or pneumonia due to shallow breathing or inadequate lung expansion. Coughing and deep breathing exercises help to clear secretions, improve lung function, and prevent respiratory complications. It is typically recommended to perform these exercises every hour to maintain lung expansion and prevent complications.
D. Encouraging the client to turn every 2 hours (D), not every 4 hours, is essential to prevent pressure ulcers and promote circulation.
E. Postoperative pain management is essential for the client's comfort and recovery. Pain can interfere with the client's ability to cough, deep breathe, and move effectively, which may increase the risk of complications. Administering analgesics as needed helps to control pain, improve overall comfort, and promote participation in necessary activities such as coughing, deep breathing, and turning.

A. Troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart. B. Troponin is an enzyme that indicates damage to brain, heart, and skeletal muscle tissues. C. Troponin is a protein that helps transport oxygen throughout the body. D. Troponin is a lipid whose levels reflect the risk for coronary artery disease.

Correct Answer is A

Explanation

A. Troponin is a protein found in cardiac muscle cells. When there is damage to the heart muscle, such as during a myocardial infarction (heart attack), troponin is released into the bloodstream. Therefore, elevated troponin levels in the blood indicate myocardial injury or damage.
B. Troponin is not an enzyme; it is a protein. While there are enzymes such as creatine kinase (CK) and lactate dehydrogenase (LDH) that can indicate damage to various tissues including heart and skeletal muscles, troponin specifically indicates cardiac muscle damage.
C. Troponin is not involved in oxygen transport. Hemoglobin, found in red blood cells, is the protein responsible for oxygen transport in the body.
D. Troponin is not a lipid; it is a protein. Lipids include substances like cholesterol and triglycerides. Troponin levels do not reflect the risk for coronary artery disease; rather, they indicate acute damage to the heart muscle.
