MULTIPLE CHOICE

1. The nurse keeps the environment warmer for older adults because they are more sensitive to cold because of the age-related changes in their:

  1. metabolism rate.
  2. subcutaneous tissue.
  3. musculoskeletal system.
  4. 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.

2. The nurse reassures the distressed 75-year-old male that the wartlike dark macules with distinct borders are not melanomas, but the skin lesions of:

  1. senile lentigo.
  2. cutaneous papillomas.
  3. seborrheic keratoses.
  4. xerosis.

ANS: C
Dark, slightly raised macules are seborrheic keratoses, which may be mistaken for melanomas.
DIF: Cognitive Level: Comprehension REF: 33 OBJ: 1
TOP: Seborrheic Keratosis KEY: Nursing Process Step: Implementation MSC: NCLEX:PhysiologicalIntegrity:PhysiologicalAdaptation

3. The nurse is accompanying a group of older adults on a July 4th outing to monitor heat prostration. Older adults are intolerant of heat because of an age-related reduction of:

  1. melanin.
  2. perspiration.
  3. body temperature.
  4. capillary fragility.

ANS: B
Reduction in perspiration related to reduced sweat gland function results in possible heat intolerance from an inability to cool the body by evaporation.

4. The nurse cautions the CNAs to use care when transferring or handling older adults because their vascular fragility will cause:

  1. altered blood pressure.
  2. pressure ulcers.
  3. pruritus.
  4. senile purpura.

ANS: D
Increased capillary fragility results in subcutaneous hemorrhage or senile purpura from incautious handling by caregivers.

5. The nurse assesses a stage I pressure ulcer on an older adult’s coccyx by the appearance of a:

  1. clear blister.
  2. nonblanchable area of erythema.
  3. scaly abraded area.
  4. painful reddened area.

ANS: B
A red nonblanchable area is indicative of a stage I pressure ulcer.
