Integumentary System Exam Questions Questions
Question 1 of 5
Identify the chemical symbol for potassium
Correct Answer: A
Rationale: The correct answer is A: K+. The chemical symbol for potassium is K, not K+. The superscript "+", indicating a positive charge, is not part of the chemical symbol. Choice B, Mg2+, represents magnesium with a 2+ charge. Choice C, Na+, represents sodium with a 1+ charge. Choice D, H+, represents a hydrogen ion. Potassium's chemical symbol is K based on its Latin name "kalium."
Question 2 of 5
Which information noted by a nurse when caring for a patient with a bladder infection is most important to report to the healthcare provider?
Correct Answer: C
Rationale: The correct answer is C: Left-sided flank pain. This symptom can indicate a possible kidney involvement, such as pyelonephritis, which is a serious complication of a bladder infection. It is important to report this symptom promptly to the healthcare provider for further evaluation and treatment to prevent complications. The other choices, Dysuria (A), Hematuria (B), and Temp 100.1F (D), are common symptoms of a bladder infection but do not suggest kidney involvement or a more severe condition requiring immediate attention.
Question 3 of 5
A nurse is assessing an obese client in the clinic for follow-up after an episode of deep vein thrombosis. The client has lost 20 pounds since the last visit. What action by the nurse is best?
Correct Answer: A
Rationale: The correct answer is A: Ask if the weight loss was intended. This is the best action because unintentional weight loss in an obese client may indicate underlying health issues. By asking if the weight loss was intended, the nurse can assess if there are any concerning factors contributing to the weight loss. Summary of other choices: B: Encouraging a high-protein, high-fiber diet may be beneficial for weight management but does not address the potential underlying causes of weight loss. C: Measuring for new compression stockings is not the priority when assessing unintended weight loss. D: Reviewing a 3-day food diary is important for overall nutrition assessment but does not directly address the reason for the weight loss.
Question 4 of 5
Integument is usually called by the proverb 'Jack of all trades' because it-
Correct Answer: D
Rationale: The correct answer is D because the integument, which includes the skin, hair, and nails, performs various functions such as protection, temperature regulation, sensation, and vitamin D production. It acts as a barrier against pathogens and UV radiation, regulates body temperature through sweat production, and contains sensory receptors for touch, pressure, and temperature. Choices A, B, and C are incorrect because while the integument does give shape to the body, protect the body, and contain growth inhibitors to some extent, these functions alone do not fully encompass the wide range of roles performed by the integument.
Question 5 of 5
Colouration of the skin depends on-
Correct Answer: D
Rationale: The correct answer is D, "All of the above." The colouration of the skin depends on the amount of blood in its blood vessels (A), as blood vessels can give the skin a pink or red hue. The inherent yellowish colour of its tissue (B) also contributes to skin colour, especially in lighter skin tones. Additionally, the amount of melanin in its tissue (C) plays a significant role in determining skin colour, with more melanin leading to darker skin tones. Therefore, all of these factors collectively influence the colouration of the skin, making option D the correct answer.
