A nurse assesses four patients. Which patient has greatest risk for hypomagnesemia?
a 41-year-old with hypernatremia
a 72-year-old with chronic alcoholism
a 79-year-old with bone cancer
a 46-year-old with respiratory acidosis
The Correct Answer is B
A) 41-year-old with hypernatremia:
Hypernatremia refers to elevated levels of sodium in the blood. While hypernatremia can lead to dehydration and electrolyte imbalances, it does not directly correlate with an increased risk of hypomagnesemia.
B) 72-year-old with chronic alcoholism:
Chronic alcoholism is a significant risk factor for hypomagnesemia. Alcohol abuse can lead to poor dietary intake of magnesium, increased renal excretion of magnesium, and impaired absorption of magnesium in the gastrointestinal tract, all contributing to magnesium deficiency.
C) 79-year-old with bone cancer:
Bone cancer does not inherently increase the risk of hypomagnesemia. However, depending on the treatment modalities and disease progression, the client may be at risk for other electrolyte imbalances or complications associated with bone cancer.
D) 46-year-old with respiratory acidosis:
Respiratory acidosis refers to an acid-base imbalance characterized by elevated levels of carbon dioxide in the blood due to impaired ventilation. While respiratory acidosis can lead to electrolyte imbalances, particularly potassium imbalances, it is not directly linked to hypomagnesemia.

Correct Answer is A
Explanation
A) Cheyne-Stokes respirations:
Cheyne-Stokes respirations are characterized by a cycle of gradually increasing and then decreasing respirations followed by a period of apnea. This pattern repeats in a regular cycle. It is commonly observed in clients with conditions affecting the central nervous system, such as traumatic brain injury, stroke, or brain tumors. Cheyne-Stokes respirations can also occur during the dying process. The alternating periods of hyperventilation and apnea result from fluctuations in oxygen and carbon dioxide levels in the blood.
B) Kussmaul respirations:
Kussmaul respirations are deep, rapid, and labored breathing patterns often observed in clients with metabolic acidosis, particularly diabetic ketoacidosis. Unlike Cheyne-Stokes respirations, Kussmaul respirations do not involve periods of apnea.
C) Apneustic respirations:
Apneustic respirations are characterized by prolonged inspiratory gasps followed by insufficient expiration. This irregular breathing pattern typically indicates damage to the pons, a part of the brainstem involved in regulating breathing. Apneustic respirations are different from the pattern described in the scenario.
D) Stridor:
Stridor is a high-pitched, noisy respiratory sound heard on inspiration that indicates upper airway obstruction, such as from swelling, foreign body aspiration, or tumors. It is not associated with the alternating pattern of hyperventilation and apnea described in Cheyne-Stokes respirations.
Correct Answer is B
Explanation
A) Reduced respiratory rate:
Acute pain typically triggers an increased respiratory rate rather than a reduced one. Pain activates the sympathetic nervous system, leading to increased respiratory effort as the body prepares to fight or flee.
B) Elevated blood pressure:
Elevated blood pressure is a common physiological response to acute pain. Pain activates the sympathetic nervous system, leading to the release of stress hormones like adrenaline, which constrict blood vessels and increase heart rate and blood pressure.
C) Constricted pupils:
Pain often causes pupil dilation rather than constriction. The body's fight-or-flight response to pain involves pupil dilation to enhance visual acuity and peripheral vision, allowing individuals to detect potential threats in their environment.
D) Decreased heart rate:
Acute pain typically results in an increased heart rate rather than a decreased one. Pain triggers the release of adrenaline, which increases heart rate as part of the body's stress response to prepare for action.
