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

Hypertension

Cerebral edema

Muscle weakness

Hyperactive bowel sounds

Answer and Explanation

The Correct Answer is C

The correct answer is c. Muscle weakness.

Choice A: Hypertension

Reason: Hypertension, or high blood pressure, is not a typical manifestation of hypokalemia. Hypokalemia primarily affects muscle function and the nervous system. While potassium imbalances can influence blood pressure, hypertension is more commonly associated with hyperkalemia (high potassium levels) rather than hypokalemia.

Choice B: Cerebral Edema

Reason: Cerebral edema, which is swelling of the brain, is not a known manifestation of hypokalemia. Hypokalemia affects muscle and nerve function, but it does not directly cause cerebral edema. This condition is more related to severe head injuries, infections, or other medical conditions.

Choice C: Muscle Weakness

Reason: Muscle weakness is a common and significant manifestation of hypokalemia. Potassium is crucial for muscle function, and low levels can lead to muscle weakness, cramps, and even paralysis in severe cases. This is because potassium helps in the transmission of nerve signals to muscles, and a deficiency disrupts this process.

Choice D: Hyperactive Bowel Sounds

Reason: Hyperactive bowel sounds are not typically associated with hypokalemia. In fact, hypokalemia can lead to decreased bowel motility, resulting in symptoms like constipation or ileus (a condition where the intestines do not move properly). This is due to the role of potassium in muscle contractions, including those in the digestive tract.

Correct Answer is B

Explanation

Choice A reason: The pulse oximeter might not be accurate during times of excessive movement is a correct statement, as movement can interfere with the detection of the pulse and the oxygen saturation. The parents should try to keep the infant still and calm while using the pulse oximeter.

Choice B reason: We will notify the doctor if the pulse oximeter consistently reads 100% is an incorrect statement, as it indicates a misunderstanding of the normal range of oxygen saturation. The parents should not be alarmed if the pulse oximeter reads 100%, as it means that the infant's blood is fully saturated with oxygen. The normal range of oxygen saturation for infants is 95% to 100%.

Choice C reason: The probe of the pulse oximeter can be applied to a finger or a toe is a correct statement, as these are suitable sites for measuring the oxygen saturation in infants. The parents should make sure that the probe fits snugly and securely on the infant's finger or toe.

Choice D reason: We will rotate the probe of the pulse oximeter every 24 hours is a correct statement, as it helps to prevent skin irritation, pressure ulcers, or infection from prolonged contact with the probe. The parents should also check the infant's skin regularly for any signs of redness, swelling, or pain.

A. Caffeinated beverages B. Low-fiber cereal C. White rice D. Ripe bananas

Correct Answer is A

Explanation

Choice A reason: Caffeinated beverages can cause diarrhea by stimulating the intestinal motility and increasing the fluid loss. They can also irritate the lining of the stomach and intestines.

Choice B reason: Low-fiber cereal is not likely to cause diarrhea. Fiber helps to bulk up the stool and regulate the bowel movements. Low-fiber foods are often recommended for clients with diarrhea to reduce intestinal activity.

Choice C reason: White rice is not likely to cause diarrhea. It is a bland and starchy food that can help to bind the stool and reduce fluid loss. White rice is often part of the BRAT diet (bananas, rice, applesauce, toast) that is suggested for clients with diarrhea.

Choice D reason: Ripe bananas are not likely to cause diarrhea. They are rich in potassium, which can help to replenish the electrolytes lost due to diarrhea. They also contain pectin, a soluble fiber that can help to firm up the stool.
