Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
Which of the following mechanisms restores homeostasis during periods of raised body temperature?
Correct Answer: B
Rationale: Perspiration is the correct answer as it helps to cool the body through evaporation, restoring normal body temperature. When the body temperature is elevated, sweat glands release sweat which evaporates, taking away heat from the body. Hypoventilation reduces oxygen intake, shivering generates heat, and piloerection (goosebumps) traps air to insulate the body, all of which do not directly help in cooling the body.
Question 2 of 5
What is the function of melanin?
Correct Answer: A
Rationale: The correct answer is A: To protect the skin from UV radiation. Melanin is a pigment produced by melanocytes in the skin that acts as a natural defense mechanism against UV radiation. It absorbs and scatters UV light, preventing damage to the skin cells and reducing the risk of skin cancer. Choices B and C are incorrect because while melanin does contribute to skin color, its primary function is UV protection. It also does not directly regulate body temperature. Choice D is incorrect as melanin does not regulate body temperature.
Question 3 of 5
A nurse is caring for a client who has a left renal calculus and an indwelling urinary catheter. Which of the following assessment findings requires immediate intervention by the nurse?
Correct Answer: C
Rationale: The correct answer is C: Absent urine output for 2 hours. This finding requires immediate intervention as it may indicate urinary obstruction, which can lead to serious complications like renal failure. The nurse should assess for catheter kinks, blockages, or dislodgement. Choices A, B, and D are incorrect as they are common symptoms associated with renal calculi and do not require immediate intervention. Flank pain and lower abdomen radiation are typical of renal calculi. Nausea can be due to pain or irritation caused by the calculus. Feeling sweaty may be due to pain or anxiety.
Question 4 of 5
A client has been diagnosed with a deep vein thrombosis and is to be discharged on warfarin (Coumadin). The client is adamant about refusing the drug because 'it's dangerous.' What action by the nurse is best?
Correct Answer: A
Rationale: The correct answer is A: Assess the reason behind the client's fear. This is the best action because it allows the nurse to understand the client's specific concerns and address them effectively. By exploring the client's fears, the nurse can provide personalized education and support, potentially alleviating the client's anxieties and increasing compliance. Choice B is incorrect because simply reminding the client about laboratory monitoring does not address the underlying fear. Choice C is incorrect as general statements about drug safety may not address the client's specific concerns. Choice D is also incorrect as it focuses on consequences rather than addressing the root cause of the client's refusal.
Question 5 of 5
Pigmentation of the skin is by the secretions of-
Correct Answer: C
Rationale: The correct answer is C: Melanocytes. Melanocytes are the cells responsible for producing melanin, the pigment that gives color to the skin. Monocytes, neutrophils, and eosinophils are types of white blood cells involved in immune responses and inflammation, not in pigmentation of the skin. Melanocytes specifically produce melanin, which determines the color of an individual's skin, hair, and eyes. Therefore, the secretion of melanocytes is responsible for skin pigmentation.
