A home care nurse is assisting with the care of a client.
Urinary stasis
Calcium resorption
Contractures
Hypocalcemia
Hypertension
Diarrhea
Pressure ulcer
Atelectasis
Correct Answer : A,B,C,G,H
Rationale:
• Urinary stasis: Immobility slows bladder emptying and ureteral flow, increasing residual urine. This promotes bacterial growth and risk of urinary tract infection. MS clients with decreased mobility are especially vulnerable.
• Calcium resorption: Bone demineralization occurs during prolonged immobility. Without weight-bearing, calcium is released from bone into the bloodstream, raising serum calcium and weakening bones.
• Contractures: Lack of movement leads to shortening and stiffening of muscles and joints. Over time, joints lose flexibility, especially if the client remains curled in one position.
• Hypocalcemia: The client is more likely to develop hypercalcemia due to calcium resorption from bones. There's no evidence of low calcium symptoms like tetany or numbness.
• Hypertension: The client's vital signs are within normal range. Immobility may reduce cardiac output over time, but it does not typically cause high blood pressure.
• Diarrhea: Immobility usually causes constipation due to slowed peristalsis. There's no report of active GI symptoms or triggers for diarrhea in this case.
• Pressure ulcer: Continuous pressure on one area reduces capillary blood flow. This leads to tissue ischemia and skin breakdown, especially over bony prominences like the hip and shoulder.
• Atelectasis: Lying on one side restricts lung expansion, and refusal to change positions impairs ventilation. This can cause alveolar collapse and decreased oxygen exchange.

Related Questions
Correct Answer is A
Explanation
Rationale:
A. Headaches with aura: Headaches accompanied by aura are a strong contraindication to oral contraceptive use due to the significantly increased risk of thromboembolic events, particularly ischemic stroke. Estrogen-containing contraceptives can further exacerbate this vascular risk, making alternative forms of birth control necessary.
B. Gastroesophageal reflux disease: GERD is a gastrointestinal condition that does not affect the safety or efficacy of oral contraceptives. Although hormonal fluctuations can sometimes influence gastric symptoms, GERD is not a contraindication to contraceptive use.
C. History of mononucleosis 1 year ago: A past infection with mononucleosis does not impact liver function long-term in most cases and does not interfere with hormonal contraceptive use. It does not pose any increased risk related to estrogen or progesterone components.
D. Irregular menstrual cycles: While irregular cycles are a common reason for initiating oral contraceptives, they are not a contraindication. In fact, hormonal contraceptives are often used therapeutically to regulate menstrual patterns and reduce cycle variability.
Correct Answer is A
Explanation
Rationale:
A. Swelling of the lips: Swelling of the lips can be an early sign of anaphylaxis, a severe allergic reaction. Epinephrine is the first-line treatment for anaphylaxis because it rapidly reduces airway swelling, improves breathing, and supports blood pressure by constricting blood vessels.
B. Nausea: While nausea may occur during an allergic reaction, it is not a primary life-threatening symptom addressed by epinephrine. Epinephrine targets cardiovascular and respiratory symptoms more directly, not gastrointestinal discomfort.
C. Hand tremors: Tremors are actually a potential side effect of epinephrine due to its stimulation of the sympathetic nervous system. The medication is not intended to treat tremors and may even cause or worsen them temporarily.
D. Hyperglycemia: Epinephrine can increase blood glucose levels as a side effect, but it is not prescribed to treat or manage hyperglycemia. Managing blood glucose is not part of the therapeutic purpose of this emergency medication.
