- A. Fine crackles are audible at the lung bases.
- B. Client's right calf is swollen and tender.
- C. Client is using the PCA every 15 minutes.
- D. Urine in the collection bag is amber and clear.
Correct Answer: B
Rationale: Swelling and tenderness in the calf suggest deep vein thrombosis, a serious complication requiring immediate attention.
At the level of the testicle, the efferent ducts:
- A. continue the rete testis;
- B. open in the epididymal duct;
- C. open in the deferent duct;
- D. are 30;
Correct Answer: A
Rationale: Rationale for Correct Answer A: The efferent ducts continue the rete testis. This is true because the efferent ducts are a series of small ducts that connect the rete testis to the epididymis. The rete testis is a network of tubules located at the back of the testicle where spermatozoa from the seminiferous tubules are collected. Therefore, the efferent ducts serve to transport spermatozoa from the rete testis to the epididymis for further maturation.
Summary of Incorrect Choices:
B: Opening in the epididymal duct is incorrect because the efferent ducts lead into the epididymis, not the epididymal duct itself.
C: Opening in the deferent duct is incorrect because the efferent ducts do not lead directly into the deferent duct, but rather connect the rete testis to the epididym
The outer serosal layer of the uterus is the _____.
- A. perimetrium
- B. cervix
- C. endometrium
- D. myometrium
Correct Answer: A
Rationale: The correct answer is A: perimetrium. The perimetrium is the outer serosal layer of the uterus, providing protection and support. The other choices are incorrect: B. cervix is the lower portion of the uterus, C. endometrium is the inner lining where implantation occurs, and D. myometrium is the middle muscular layer of the uterus. The perimetrium is the outermost layer, making it the correct choice.
After a rectal examination of a patient with obstructive jaundice, the nurse expects the stool to be what color?
- A. Tan
- B. Pale yellow
- C. Black
- D. Bright red
Correct Answer: A
Rationale: The correct answer is A: Tan. In obstructive jaundice, there is a blockage in the bile ducts, leading to reduced bile flow into the intestines. As a result, stool color changes to tan or clay-colored due to the absence of bile pigments. Pale yellow is incorrect as it suggests some bile flow. Black stool indicates upper gastrointestinal bleeding. Bright red stool indicates lower gastrointestinal bleeding.
How many chromosomes are present in a sperm?
- A. 1
- B. 2
- C. 12
- D. 23
Correct Answer: D
Rationale: The correct answer is D: 23. Sperm cells are haploid, meaning they contain half the number of chromosomes as normal body cells. In humans, normal body cells have 46 chromosomes (23 pairs), while sperm cells have only 23 chromosomes. This is essential for maintaining the correct chromosome number after fertilization.
A: 1 - Incorrect. Sperm cells cannot have only 1 chromosome as they need to contribute genetic material during fertilization.
B: 2 - Incorrect. Having only 2 chromosomes would not provide sufficient genetic diversity for offspring.
C: 12 - Incorrect. This number does not align with the haploid nature of sperm cells in humans with 23 chromosomes.
