Question 1 of 5
Which of the following is a normal function of the skin?
Correct Answer: D
Rationale: The skin's role in homeostasis includes temperature control, making 'thermal regulation by skin blood flow dilation or constriction'. The hypothalamus signals skin vessels to vasoconstrict e.g., conserving heat in cold (temp up 1°C) or vasodilate e.g., shedding heat in warmth (temp down 2°C) per Baranoski and Ayello (2004). , 'synthesis of vitamin K,' is false; skin makes vitamin D via UV e.g., 10 minutes sun yields 1000 IU not K, which liver produces. , 'elimination of carbon dioxide,' is lungs' job e.g., 35-45 mmHg CO2 exhaled, not skin. , 'glucose regulation by Langerhans cells,' misattributes; pancreatic islets, not skin's Langerhans (immune cells), manage glucose e.g., insulin drops 100 mg/dL. Skin's sweat and blood flow e.g., dilating vessels in 90°F heat regulate temp, a nurse's focus in fever or hypothermia. Unlike lungs or pancreas, skin's thermal role is dynamic, immediate, and measurable, aligning with essentials in *Wound Care Essentials*, making the accurate function.
Question 2 of 5
What is the primary advantage of a hydrogel dressing for wound healing?
Correct Answer: A
Rationale: The primary advantage of a 'hydrogel dressing' is to 'provide moisture needed for wound healing,' per Potter's *Essentials*. Moisture e.g., 90% water keeps granulation alive e.g., heals 50% faster unlike 'absorbent' , gauze's role e.g., drainage, not moisture. 'Negative pressure' is NPWT e.g., vacuums fluid, not hydrogel. 'Protection' fits hydrocolloids e.g., seals, not moistens. A nurse uses e.g., Hydrogel on dry wound' per wound care texts, a physiological integrity key. Potter notes moisture's debridement aid too, making the correct, core benefit.
Question 3 of 5
The nurse is working on a medical-surgical unit that has been participating in a research project associated with pressure ulcers. Which risk factor will the nurse assess for that predisposes a patient to pressure ulcer development?
Correct Answer: A
Rationale: The nurse assesses 'decreased level of consciousness' as a key pressure ulcer risk. Confused or unconscious patients e.g., post-stroke can't shift to relieve pressure e.g., 32 mmHg occludes capillaries unlike 'adequate dietary intake' , protective e.g., protein aids tissue. 'Shortness of breath' and 'muscular pain' don't directly impair repositioning e.g., not Braden factors. A nurse checks e.g., Unresponsive, still 4 hours' noting 50% higher ulcer odds, per research, needing turning. The text lists sensory perception and mobility over respiratory or pain issues, a physiological integrity focus. is the correct, predisposing factor.
Question 4 of 5
The nurse is caring for a patient who has experienced a laparoscopic appendectomy. For which type of healing will the nurse focus the care plan?
Correct Answer: D
Rationale: A laparoscopic appendectomy heals by 'primary intention'. Small, closed incisions e.g., 1 cm approximate fast e.g., 7 days unlike 'partial-thickness' , shallow e.g., abrasions. 'Secondary intention' is open e.g., burns. 'Tertiary intention' delays e.g., infection risk. A nurse plans e.g., Suture care' per 90% of surgeries, a physiological focus. The text defines primary as low-risk, making the correct, surgical healing.
Question 5 of 5
The nurse is completing an assessment on a patient with a Stage IV pressure ulcer. The wound is odorous, and a drain is currently in place. Which statement by the patient indicates issues with self-concept?
Correct Answer: C
Rationale: I am ready for my bath and linen change right now since this is awful' shows self-concept issues, per *Fundamentals*. Odor e.g., from Stage IV hints shame e.g., 60% report distress unlike 'weak, tired' , physical e.g., not image. 'Ready to go home' is positive e.g., hope. 'Good dinner' is neutral e.g., appetite. A nurse hears e.g., Awful smell' per body image impact, a psychosocial focus. The text links odor to esteem, making the correct, self-concept clue.
