A nurse is collecting data on a client who has diarrhea. Which of the following findings is a manifestation of hypokalemia?

Choice A reason: The nurse applies the sterile drape prior to cleansing the perineal area. This is a correct action by the nurse, as it helps to prevent contamination of the catheter insertion site and maintain a sterile field.

Choice B reason: The nurse coats the indwelling urinary catheter with lubricant. This is a correct action by the nurse, as it helps to ease the insertion of the catheter and reduce the risk of trauma or infection.

Choice C reason: The nurse separates the client's labia with her dominant hand. This is an incorrect action by the nurse, as it violates the principle of sterile technique. The nurse should use her non-dominant hand to separate the labia and expose the urethral meatus, and use her dominant hand to hold the catheter. The non-dominant hand should not touch anything else after separating the labia, as it is considered contaminated.

Choice D reason: The nurse provides perineal care prior to inserting the urinary catheter. This is a correct action by the nurse, as it helps to reduce the bacterial load and prevent infection. The nurse should use soap and water to cleanse the perineal area from front to back, and use a new washcloth for each stroke.

Choice A reason: Flank pain is not a sign of an allergic transfusion reaction. Flank pain is a pain in the side of the abdomen or back, usually caused by kidney problems, such as infection, stones, or injury. Flank pain can be a sign of a hemolytic transfusion reaction, which is a serious complication that occurs when the donor blood is incompatible with the recipient's blood type.

Choice B reason: Elevated blood pressure is not a sign of an allergic transfusion reaction. Elevated blood pressure is a condition where the force of the blood against the artery walls is too high, which can increase the risk of heart disease, stroke, and kidney damage. Elevated blood pressure can be a sign of a hypertensive transfusion reaction, which is a rare complication that occurs when the donor blood has a higher sodium level than the recipient's blood.

Choice C reason: Distended neck veins are not a sign of an allergic transfusion reaction. Distended neck veins are a sign of increased pressure in the right side of the heart or the superior vena cava, which can be caused by heart failure, pulmonary hypertension, or obstruction. Distended neck veins can be a sign of a circulatory overload transfusion reaction, which is a complication that occurs when the blood volume or rate of infusion is too high for the recipient's cardiovascular system.

Choice D reason: Wheezing is a sign of an allergic transfusion reaction. Wheezing is a high-pitched whistling sound that occurs when the airways are narrowed or inflamed, which can cause difficulty breathing, coughing, or chest tightness. Wheezing can be a sign of an allergic transfusion reaction, which is a hypersensitivity response to the donor blood or its components, such as plasma proteins, antibodies, or preservatives. An allergic transfusion reaction can range from mild to severe, and can be treated with antihistamines, corticosteroids, or epinephrine.
