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 ["31"]

Explanation

Step 1 is: Convert hours to minutes: 8 hours × 60 minutes/hour = 480 minutes.

Step 2 is: Calculate the drops/minute: (1000 mL ÷ 480 minutes) × 15 gtts/mL.

Step 3 is: Perform the division: 1000 mL ÷ 480 minutes ≈ 2.0833 mL/min.

Step 4 is: Perform the multiplication: 2.0833 mL/min × 15 gtts/mL ≈ 31.25 drops/min.

Step 5 is: Round the answer to the nearest whole number: 31 drops/min.

Final calculated answer: 31 drops/min.

A. A condition in which there is a puncture or rupture of the lung. B. A condition characterized by the presence of air or gas in the pleural cavity. C. A condition characterized by multiple fractures of the ribs resulting in a segment of the chest wall becoming detached. D. A condition characterized by the collapse of the lung.

Correct Answer is C

Explanation

Choice A rationale

A puncture or rupture of the lung is typically associated with a pneumothorax, not flail chest. Pneumothorax occurs when air leaks into the space between the lung and the chest wall.

Choice B rationale

The presence of air or gas in the pleural cavity is known as pneumothorax. Flail chest, however, is characterized by multiple rib fractures.

Choice C rationale

Flail chest occurs when multiple adjacent ribs are fractured in multiple places, creating a free-floating segment of the chest wall. This condition is serious and often results from blunt chest trauma.

Choice D rationale

The collapse of the lung is known as atelectasis or pneumothorax, not flail chest. Flail chest specifically refers to the detachment of a segment of the rib cage.
