Questions on the Integumentary System Questions
Question 1 of 5
Which of the following is a holocrine exocrine gland?
Correct Answer: D
Rationale: The correct answer is D: sebaceous gland. Sebaceous glands are holocrine glands, where entire cells are released with their secretions. The sebaceous glands produce sebum by the disintegration of entire cells, a characteristic of holocrine secretion. A: Merocrine glands release secretions through exocytosis, not by disintegration of cells. B: Ceruminous glands produce earwax and are classified as modified apocrine glands. C: Apocrine glands release secretions along with a part of the cell cytoplasm, not the entire cell.
Question 2 of 5
________ hairs are coarse pigmented hairs.
Correct Answer: B
Rationale: The correct answer is B: Terminal. Terminal hairs are coarse, pigmented hairs found on the scalp, eyebrows, and eyelashes. This type of hair is fully developed and thicker compared to vellus hairs found on other areas of the body. Keratinous (A) refers to the protein that makes up hair, so it is not describing the type of hair. Follicular (C) pertains to the hair follicle itself and not the type of hair. Dense (D) does not specify the characteristics of the hair, so it is not the correct choice. Therefore, B is the correct answer.
Question 3 of 5
Each of the following is a function of the integumentary system except
Correct Answer: A
Rationale: The correct answer is A: synthesis of vitamin C. The integumentary system does not synthesize vitamin C; it is produced by the liver. The integumentary system's function includes maintaining body temperature, providing sensation, and protecting underlying tissues. Vitamin C synthesis is not a function of the integumentary system as it is primarily related to the liver's metabolic processes. Therefore, choice A is the correct answer as it does not align with the functions of the integumentary system.
Question 4 of 5
All of the following are characteristics of the epidermis except that it
Correct Answer: A
Rationale: Correct Answer: A (is vascularized) Rationale: The epidermis is avascular, meaning it does not contain blood vessels. This is crucial for protection against external factors. The other choices are correct: B) It is multilayered to provide protection, C) It is flexible to allow for movement, and D) It is self-repairing to heal minor injuries. Summary: - A: Incorrect, as the epidermis lacks blood vessels for protection. - B: Correct, as the epidermis is multilayered for protection. - C: Correct, as the epidermis is flexible for movement. - D: Correct, as the epidermis has self-repairing capabilities.
Question 5 of 5
As charge nurse in a long-term-care (LTC) facility, you are developing a care plan for a client with a stage 3 pressure ulcer located over the sacrum. Which nursing intervention is most appropriate to delegate to an LPN who works as a team leader in the facility?
Correct Answer: D
Rationale: The correct answer is D: Inspect and document the appearance of the ulcer daily. Delegating this task to an LPN is appropriate as it involves routine monitoring and documentation of the pressure ulcer, which is within the scope of practice for an LPN. By inspecting and documenting the ulcer daily, the LPN can track any changes in the ulcer's appearance, such as signs of infection or healing progress, and report this information to the charge nurse or healthcare provider. This helps in ensuring proper wound care and timely intervention. Choice A (Choosing the type of dressing) involves making a clinical decision that requires a higher level of assessment and expertise, typically done by an RN or wound care specialist. Choice B (Using the Norton scale for assessment) involves a comprehensive assessment of risk factors, which is more suitable for an RN. Choice C (Assisting the client to change position) involves direct client care and should be done by a nursing assistant under the supervision of an RN or LPN.
