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
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 C
Explanation
Choice A reason: Storing oxygen tanks upright is not a necessary instruction for home oxygen therapy. Oxygen tanks can be stored horizontally or vertically, as long as they are secured and away from heat sources.
Choice B reason: Using petroleum-based ointments to moisturize lips is not advisable for clients who use home oxygen therapy. Petroleum-based products can ignite in the presence of oxygen and cause burns. The nurse should recommend water-based products instead.
Choice C reason: Keeping oxygen tanks 4 feet away from an electric stove is a safety measure for home oxygen therapy. Oxygen is a flammable gas and can cause a fire or explosion if exposed to heat or sparks. The nurse should also instruct the client to avoid smoking, candles, and other open flames.
Choice D reason: Choosing a wool blanket when using oxygen is not a good idea for home oxygen therapy. Wool is a synthetic material that can generate static electricity and ignite oxygen. The nurse should suggest cotton or other natural fabrics instead.
Correct Answer is A
Explanation
Choice A reason: Leakage of urine is a sign of urinary retention, as it indicates that the bladder is overdistended and unable to empty completely. The urine may leak around the urethra or through a catheter.
Choice B reason: Dark-colored urine is not a sign of urinary retention. It can be caused by dehydration, certain foods or medications, or liver or kidney problems.
Choice C reason: Cloudy urine is not a sign of urinary retention. It can be caused by infection, inflammation, or stones in the urinary tract.
Choice D reason: Blood in urine is not a sign of urinary retention. It can be caused by trauma, infection, cancer, or coagulation disorders in the urinary tract.
