Which condition in men is termed as Nongonococcal urethritis?
- A. Chlamydia
- B. Gonorrhea
- C. Herpes
- D. Syphilis
Correct Answer: A
Rationale: The correct answer is A: Chlamydia. Nongonococcal urethritis is primarily caused by Chlamydia trachomatis, a common sexually transmitted infection. Chlamydia is a major cause of urethritis in men. Gonorrhea (choice B) is another sexually transmitted infection but is not classified as nongonococcal urethritis. Herpes (choice C) and Syphilis (choice D) are caused by different pathogens and present with distinct symptoms, not typically associated with urethritis. Therefore, Chlamydia is the correct choice for Nongonococcal urethritis.
You obtain all of these assessment data about your client with continuous bladder irrigation (CBI) after a transurethral resection of the prostate (TURP). Which information indicates the most immediate need for nursing intervention?
- A. The client states he feels a continuous urge to void.
- B. The catheter drainage is light pink with occasional clots.
- C. The catheter is pulled taut and taped to the client's thigh.
- D. The client complains of painful bladder spasms.
Correct Answer: D
Rationale: Painful bladder spasms can indicate complications such as clot formation or obstruction, requiring immediate attention.
Choose the CORRECT match. Animals Fertilization Embryonic development
- A. Dog Internal Oviparity
- B. Duck External Viviparity
- C. Frog External Oviparity
- D. Cat Internal Ovoviviparity
Correct Answer: C
Rationale: The correct match is C: Frog - External Oviparity. Frogs lay eggs externally, and their fertilization and embryonic development occur outside the female's body. This is characteristic of oviparous animals. The other choices are incorrect because:
A: Dog - Internal Oviparity, dogs give birth to live young and do not lay eggs.
B: Duck - External Viviparity, ducks also give birth to live young and do not lay eggs externally.
D: Cat - Internal Ovoviviparity, cats give birth to live young but retain eggs inside their body until they hatch.
Haversian canals are seen in
- A. Cortical bone
- B. Cancellous bone
- C. Spongy bone
- D. N/A
Correct Answer: A
Rationale: The correct answer is A: Cortical bone. Haversian canals are found in cortical bone, which is the dense outer layer of bone tissue. These canals contain blood vessels, nerves, and lymphatics, allowing for the exchange of nutrients and waste products. Cancellous bone (B) is spongy bone with a network of trabeculae and does not contain Haversian canals. Spongy bone (C) is a type of bone tissue with a porous structure but lacks the organized Haversian system seen in cortical bone. "N/A" (D) is not a valid option as it does not provide any relevant information.
If a cell has 92 chromosomes at the beginning of mitosis, determine the number of chromatids at
- A. 23 chromatids
- B. 92 chromatids
- C. 46 chromatids
- D. 184 chromatids
Correct Answer: C
Rationale: The correct answer is C: 46 chromatids. At the beginning of mitosis, each chromosome consists of two sister chromatids. Since the cell has 92 chromosomes, the total number of chromatids will be 92 chromosomes x 2 chromatids per chromosome = 184 chromatids. However, this number represents the total number of chromatids, not the number at the beginning of mitosis. At the beginning of mitosis, the sister chromatids are still attached, so we need to divide the total number of chromatids by 2 to get the number at the beginning of mitosis, which is 184 chromatids / 2 = 92 chromatids. Therefore, the correct answer is 46 chromatids, as each chromosome consists of two chromatids at the beginning of mitosis. Choices A, B, and D are incorrect as they do not consider the concept of sister chromatids in chromosomes during mitosis.
