Nokea
The nurse is administering a medication to a client who is suffering from pain related to partial thickened burns. The medication will interrupt the sensation and transmission of pain stimuli. What type of nociceptors will this medication block?
- A. Thermoreceptors
- B. Mechanoreceptors
- C. Nociceptors
- D. Alpha receptors
Correct Answer: C
Rationale: Nociceptors sense and transmit the location of pain stimuli. Thermoreceptors perceive sensations of heat and cold. Mechanoreceptors detect touch, location, pressure, motion, vibration, size, and texture. Alpha receptors trigger autonomic responses.

The nurse is assessing a client who is hospitalized for dehydration from persistent vomiting. How would the nurse assess that the client's skin turgor is related to the state of dehydration?
- A. When the nurse pinches up skin of the hand, there is rapid recoil.
- B. The client has wrinkles of the chest.
- C. The nurse grasps the skin over the sternum between the thumb and forefinger with slow recoil observed.
- D. The nurse grasps the skin over the sternum between the thumb and forefinger with rapid recoil observed.
Correct Answer: C
Rationale: Poor skin turgor, indicated by slow recoil when the skin over the sternum is pinched, suggests dehydration. Rapid recoil indicates normal hydration. Wrinkles on the chest are not a specific indicator of dehydration.
Which of the following conditions is the cause of thickening of the nail?
- A. Fungal infection
- B. Long-standing pulmonary disease
- C. Myocardial infarction
- D. Iron-deficiency anemia
Correct Answer: A
Rationale: Long-standing poor circulation leads to nail thickening, especially of the lower extremities. Nails thicken when there is a fungal infection and poor circulation. Clubbing of the nails suggests a long-standing cardiopulmonary disease. Concave-shaped nails are a sign of iron-deficiency anemia. Myocardial infarction does not cause thickening of nails.
Which of the following pigments influences hair color?
- A. Pheromones
- B. Keratin
- C. Seburin
- D. Melanin
Correct Answer: D
Rationale: Melanin, produced by the melanocytes in the hair roots, influences hair color. Pheromones are hormone-like chemicals that communicate reproductive and social information among the lower animal species. Seburin is a lubricant that prevents drying and cracking of the skin and hair. Keratin is a tough protective protein.
An older adult client is brought to the emergency department reporting having become overheated while sitting in the sun. The client states, 'But I wasn't even perspiring.' What occurs in older adults that decreases spontaneous sweating and makes them vulnerable to heat?
- A. Decrease in the number of eccrine glands
- B. Increase in the number of eccrine glands
- C. Decreased number of apocrine glands
- D. Increased number of apocrine glands
Correct Answer: A
Rationale: A decline in the number of eccrine glands, along with decreased cutaneous vascularity, causes a decrease in spontaneous sweating with age, this makes older persons more vulnerable to heat. Apocrine glands are found around the nipples, in the anogenital region, in the eyelids, in the mammary glands of the breast, and in the external ear canals where the secretion is referred to as cerumen.
During a routine checkup, a nurse observes the client's skin to be tight and shiny. Which of the following is the correct indication of this sign?
- A. Sebum deficiency
- B. Fluid retention
- C. Dehydration
- D. Protein deficiency
Correct Answer: B
Rationale: Tight, shiny skin suggests fluid retention. Loose, dry skin may indicate dehydration. Tight, shiny skin does not suggest protein deficiency or sebum deficiency.
