A nurse is reinforcing discharge teaching with the parents of an infant who has a prescription for home oxygen and pulse oximetry monitoring. Which of the following statements by the parents indicates a need for further teaching?

Choice A reason: Stripping the client's chest tube every 2 hours is not a recommended action, as it can cause excessive negative pressure, tissue trauma, and pain. The nurse should only strip the chest tube if there is a clot or obstruction in the tubing, and only with the provider's order.

Choice B reason: Looping the tubing of the chest tube on the client's bed is a correct action, as it prevents kinking, tension, or pulling on the chest tube. The nurse should also secure the tubing to the bed sheet with a safety pin.

Choice C reason: Placing the chest tube drainage system above the level of the client's heart is not a correct action, as it can cause the fluid to flow back into the chest cavity and impair lung expansion. The nurse should place the chest tube drainage system below the level of the client's chest.

Choice D reason: Taping the connections on the client's chest tube is a correct action, as it prevents air leaks, disconnections, or accidental removal of the chest tube. The nurse should also check the connections regularly for tightness and patency.

The correct answer is b. Decreased deep tendon reflexes.

Choice A: Wheezing

Reason: Wheezing is typically associated with respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), or allergic reactions. It is not a common manifestation of hyperkalemia. Hyperkalemia primarily affects the muscular and cardiovascular systems rather than the respiratory system.

Choice B: Decreased deep tendon reflexes

Reason: Hyperkalemia can cause neuromuscular symptoms, including muscle weakness and decreased deep tendon reflexes. High potassium levels interfere with the normal function of muscle cells and nerves, leading to these symptoms. This is a direct result of the altered action potentials in neurons caused by elevated potassium levels.

Choice C: Hypoactive bowel sounds

Reason: Hypoactive bowel sounds are generally associated with conditions that cause decreased gastrointestinal motility, such as ileus or bowel obstruction. While hyperkalemia can affect muscle function, it is more likely to cause hyperactive bowel sounds due to increased gastrointestinal motility rather than hypoactive sounds.

Choice D: Cerebral edema

Reason: Cerebral edema is swelling of the brain and is not a typical manifestation of hyperkalemia. It is more commonly associated with conditions such as traumatic brain injury, stroke, or severe infections. Hyperkalemia primarily affects the heart and muscles.
