ATI RN
Integumentary System Multiple Choice Questions and Answers Questions
Question 1 of 5
Which of the following organelles produces ATP?
Correct Answer: B
Rationale: The correct answer is B: Mitochondria. Mitochondria are known as the powerhouse of the cell and generate ATP through cellular respiration. They contain specialized structures like the electron transport chain and ATP synthase which are involved in ATP production. Centrioles (A) are involved in cell division, lysosomes (C) contain digestive enzymes, and Golgi complex (D) is responsible for processing and packaging proteins, none of which are directly involved in ATP production.
Question 2 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 3 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 4 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.
Question 5 of 5
In rabbit the melanin is contained in highly specialized stellate cells called-
Correct Answer: B
Rationale: The correct answer is B: Melanocytes. Melanocytes are the cells responsible for producing melanin, the pigment that gives color to skin, hair, and eyes. In rabbits, melanin is contained in these specialized cells, not in chromatophores (A), which are found in fish and amphibians. Melanin granules (C) are the actual pigment produced by melanocytes, not the cells themselves. Carotene granules (D) are unrelated to melanin production and are responsible for the orange color in some animals. Therefore, the correct answer is B as melanocytes are specifically responsible for producing melanin in rabbits.
