The nurse is aware that clients who prefer indoor activities to outdoor activities are at risk for which vitamin deficiency?

Answer and Explanation

The Correct Answer is A

A. Vitamin D is often referred to as the "sunshine vitamin" because the body produces it in response to sunlight exposure on the skin. Spending more time indoors reduces sunlight exposure, which can lead to insufficient production of vitamin D in the body. Vitamin D is important for bone health, immune function, and other physiological processes.

B. Vitamin E deficiency is rare in healthy individuals with a balanced diet. It is primarily found in foods such as nuts, seeds, and vegetable oils. Deficiency can occur in conditions where fat absorption is impaired or in certain genetic disorders.

C. There are several B vitamins (e.g., B1, B2, B6, B12) that are essential for various metabolic processes in the body. Deficiencies in specific B vitamins can occur due to inadequate dietary intake, malabsorption

disorders, or other medical conditions. However, preference for indoor activities does not directly correlate with increased risk of vitamin B deficiency.

D. Vitamin A deficiency is more commonly associated with inadequate intake of foods rich in vitamin A (e.g., liver, carrots, sweet potatoes) rather than sunlight exposure. Vitamin A is important for vision, immune function, and cellular growth.

Correct Answer is A

Explanation

A. Confusion can be an early sign of hypoxia, especially when oxygen delivery to the brain is compromised. Inadequate oxygenation can affect cognitive function and mental status, leading to confusion. This occurs because the brain is highly sensitive to changes in oxygen levels.

B. Apnea refers to the absence of breathing. While severe hypoxia can lead to respiratory arrest and apnea, it is not typically an early manifestation of hypoxia. Early hypoxia is characterized by attempts to increase ventilation to compensate for decreased oxygen levels, rather than complete cessation of breathing.

C. Cyanosis occurs when there is a bluish discoloration of the skin and mucous membranes due to deoxygenated hemoglobin in the blood. Cyanosis is a late sign of hypoxia and usually indicates significant oxygen deprivation. It is not typically seen in early hypoxia stages.

DDysrhythmias (irregular heart rhythms) can occur as a result of hypoxia, especially if the heart muscle is not receiving enough oxygen. However, dysrhythmias are generally considered a later manifestation of hypoxia, as the heart attempts to compensate for decreased oxygen delivery.

A. hypovolemic. B. bradycardic. C. deficient. D. thready.

Correct Answer is D

Explanation

D. A "thready" pulse is weak and difficult to palpate. It feels like a fine thread or string under the fingertips and suggests poor cardiac output or decreased peripheral perfusion. A thready pulse is palpable but weak, indicating inadequate stroke volume with each heartbeat.

A. Hypovolemic refers to a state of decreased blood volume, which can lead to a weak and rapid pulse due to reduced blood flow through the arteries. However, it does not specifically describe the quality of the pulse that is palpable.

B. Bradycardia refers to a slow heart rate, typically below 60 beats per minute in adults. A bradycardic pulse may be slow but can still be strong or weak depending on the underlying cause. It does not specifically describe the quality of a weak but palpable pulse.

C. "Deficient" is not a commonly used term to describe the quality of a pulse. It does not provide specific information about the palpable nature or strength of the pulse.
