A nurse is collecting data from a client who is in renal failure. The nurse should identify that which of the following findings is a manifestation of hyperkalemia?
Dry mucous membranes
Trousseau's sign
Hyperactive reflexes
Irregular heart rate
The Correct Answer is D
Hyperkalemia refers to an elevated level of potassium in the blood. It can have various manifestations, and one of the critical effects of hyperkalemia is its impact on cardiac function. High levels of potassium can disrupt the normal electrical conduction in the heart, leading to arrhythmias or irregular heart rate. These arrhythmias can range from mild palpitations to more severe and life-threatening conditions like ventricular fibrillation.
Dry mucous membranes are more commonly associated with dehydration or reduced fluid intake. Hyperkalemia does not directly cause dry mucous membranes.
Trousseau's sign is a clinical manifestation of hypocalcemia, not hyperkalemia. It is characterized by carpal spasm induced by inflating a blood pressure cuff above the client's systolic blood pressure for a few minutes.
Hyperactive reflexes are commonly seen in conditions such as hyperthyroidism or certain neurologic disorders. They are not directly related to hyperkalemia.

Correct Answer is B
Explanation
Bran muffins are a good choice for relieving constipation because they are high in dietary fiber. Fiber adds bulk to the stool and helps promote regular bowel movements. It can soften the stool, making it easier to pass.
Puffed rice cereal is a low-fiber food and may not provide significant relief for constipation. It is typically low in fiber and may not help in promoting regular bowel movements.
Tomato juice, while a healthy choice, is not particularly high in fiber. It contains some fiber, but not as much as other options like bran muffins.
Cottage cheese is a good source of protein, but it is not known for its high fiber content. While it can be a part of a balanced diet, it may not have a significant impact on relieving constipation.
Correct Answer is A
Explanation
A. Protein supports tissue repair, maintains muscle mass, and provides sustained energy. Leukemia and its treatments can lead to muscle wasting and general weakness, so additional protein can help counteract these effects and improve energy levels. It is also essential for immune support as well.
B.Increasing fluids to 4 L per day is generally excessive and may not be appropriate for this client. Excessive fluid intake can place strain on the cardiovascular system, which could be problematic, especially if the client is receiving chemotherapy or other treatments that may impact fluid balance.
C.Continual bed rest is not recommended, as it can contribute to deconditioning, muscle atrophy, and worsening fatigue over time. While rest periods are essential for clients experiencing fatigue, it is equally important to incorporate balanced, low-intensity activity to maintain strength and circulation.
D.Such exercises require significant energy and exertion, which might not be tolerable and could exacerbate fatigue. Instead, gentle, low-impact activities like walking or stretching are more appropriate for maintaining function without overwhelming the client’s energy reserves.
