MULTIPLE CHOICE

1. Why does the nurse modify the environment to keep it warmer for the older adult?
a. A change in the metabolic rate
b. Decreased subcutaneous tissue
c. Changes in the musculoskeletal system
d. A weakened peripheral vascular system
ANS: B
The reduction of subcutaneous tissue as an age-related change causes sensitivity to cold because it is the main insulator of the body.

6. The Certified Nursing Assistant (CNA) caring for an older adult asks if the yellow, waxy, crusty lesions on the patient’s axilla and groin are contagious. Which response shows the nurse’s understanding for the cause of the lesions?
a. “Yes. It is cellulitis caused by bacteria.”
b. “No. It is seborrheic dermatitis caused by excessive sebum.”
c. “Yes. It is an indication of scabies.”
d. “No. It is the lesion seen with basal cell carcinoma.”
ANS: B
Seborrheic dermatitis is a bothersome skin condition resulting from an excess of sebum.

7. Why would a nurse lead a group of postmenopausal women on a daily 15-minute “walking tour” through the long-term care facility?
a. To improve bone strength
b. To orient them to their surroundings
c. To improve their socialization
d. To increase their appetite
ANS: A
Stress to long bones by weight-bearing and walking will increase bone strength.

8. A 70-year-old woman asks, “How in the world can my bones be brittle when I eat all the right foods?” Which response by the nurse would be the most informative?
a. “Calcium loss is expected in the older adult.”
b. “Calcium is continuously withdrawn from bone for nerve and muscle function.”
c. “Smoking and alcohol consumption speed calcium loss from the bones.”
d. “Walking and standing increase calcium loss from the bone.”
ANS: B
Calcium is constantly withdrawn from the bone for nerve and muscle function and clotting needs.

9. A 70-year-old woman complains, “I weigh exactly the same as I did when I wore a size 10 and now I can barely squeeze into a size 16.” Which statement by the nurse would most correctly explain the size change to the woman?
a. “Metabolism in the older adult creates increased adipose tissue.”
b. “Postmenopausal women gain adipose tissue related to loss of calcium.”
c. “Decrease in muscle mass is replaced with adipose tissue.”
d. “Kyphosis causes a redistribution of weight.”
ANS: C
Decrease in muscle mass is replaced with adipose tissue, which frequently changes the appearance of the body, but not the weight.

10. What would be the most helpful response to a 70-year-old postmenopausal woman who asks whether her hormone replacement therapy (HRT) will prevent bone loss?
a. “No. HRT is not helpful after the age of 60.”
b. “Yes. HRT will prevent bone loss but can cause a stroke, heart attack, or breast cancer.”
c. “No. HRT is reliant on some natural estrogen production from the ovaries.”
d. “Yes. HRT is a widely accepted therapy for prevention of bone loss.”
ANS: B
HRT is helpful to prevent bone loss, but the risks of cardiovascular complications and cancer have made the choice of HRT controversial.

11. What are Heberden nodes?
a. Yellow longitudinal lines in the nails
b. Thickened discolored fingernails
c. Darkened areas under the fingernail
d. Bony enlargements of distal joints of the fingers

12. Which care plan modification would be the most beneficial for a 62-year-old woman who is suffering from a flare in her rheumatoid arthritis?
a. Increase fluid intake
b. Schedule several rest periods to balance activity
c. Reduce salt in the diet
d. Assist with rigorous finger extension exercises
ANS: B
Balancing rest and activity allows the resident to remain relatively flexible. Joints may be splinted to reduce contracture.

13. What is the pathophysiology of emphysema?
a. Constriction of the bronchial tree, excessive mucus, and nonproductive cough
b. Calcification of the alveoli and a dry cough
c. Overinflation of the alveoli, making them ineffective for gas exchange
d. Inflammation of the trachea and bronchioles, excessive mucus, and productive cough
ANS: C
Emphysema causes overinflation of the nonelastic alveoli, which disallows gas exchange in the affected alveoli and results in reduced oxygenation.

b. The coronary vessels are narrowed during the attack.
c. The ischemic myocardium causes pain during the attack but is able to regenerate.
d. There is damage to the myocardium but no serious alteration of cardiac output.
ANS: A
The myocardium necroses and scars and does not regenerate. The degree of heart damage is related to the amount of necrosis.
