A client is admitted to the emergency department with a magnesium level of 1.2 mg/dL. The nurse is aware that a likely cause of the value is which of the following:

Alcoholism.

Dehydration.

Kidney failure.

Excessive magnesium intake.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Alcoholism is a common cause of hypomagnesemia due to poor dietary intake, increased renal excretion, and gastrointestinal losses. Chronic alcohol consumption leads to malnutrition and loss of magnesium through the urine, contributing to low magnesium levels.

Choice B rationale

Dehydration typically leads to hemoconcentration, which can elevate, rather than decrease, magnesium levels. Thus, it is not usually associated with low magnesium levels.

Choice C rationale

Kidney failure generally causes hypermagnesemia, not hypomagnesemia, because the kidneys cannot efficiently excrete magnesium, leading to its accumulation in the blood.

Choice D rationale

Excessive magnesium intake would result in hypermagnesemia, not hypomagnesemia, as the body accumulates more magnesium than it can excrete.

Correct Answer is A

Explanation

Choice A rationale

Having the patient lift their back and buttocks using a trapeze allows for proper assessment of pressure areas and skin care. This technique reduces the risk of further injury or discomfort and provides better access for the nurse to assess the skin condition.

Choice B rationale

Asking the patient to turn to the side independently may not be feasible for a patient with a pelvic fracture. This method can cause pain and risk further injury, making it an unsuitable choice for assessing pressure areas.

Choice C rationale

Rolling the patient over to the side by pushing on the patient's hip is not recommended as it can exacerbate the injury and cause pain. This method is not appropriate for patients with pelvic fractures.

Choice D rationale

Deferring back assessment until the patient is ambulatory is not a safe practice. Pressure areas should be regularly assessed to prevent skin breakdown and complications, even if the patient is not yet ambulatory.

A. To provide essential nutrients while allowing the bowel to rest and heal. B. To reduce inflammation and control symptoms of IBD. C. To stimulate the bowel and promote regular bowel movements. D. To prevent malnutrition and promote weight gain.

Correct Answer is A

Explanation

Choice A rationale

Total parenteral nutrition (TPN) provides essential nutrients intravenously, allowing the bowel to rest and heal, which is important in the management of inflammatory bowel disease (IBD).

Choice B rationale

While reducing inflammation and controlling symptoms are important goals in IBD management, TPN is primarily used to provide nutrition and allow the bowel to rest.

Choice C rationale

Stimulating the bowel is not the purpose of TPN. TPN is used to give the digestive tract a break while ensuring the patient receives necessary nutrients.

Choice D rationale

Preventing malnutrition and promoting weight gain are secondary benefits of TPN, but the primary rationale is to provide nutrients while allowing the bowel to rest and heal.
