Correct Answer: B

Rationale: The correct answer is B (AB). AB blood type is the rarest because it is a result of inheriting both A and B alleles, making it less common in the population. AB individuals can only receive blood from other AB individuals due to their unique antigens. Blood types A, B, and O are more common in the population, with O being the most common as it is the universal donor. Blood type A and B are more common than AB since they only require one allele for their respective antigens. Thus, the rarity of AB blood type is due to the inheritance of both A and B alleles, making it the least common among the choices provided.

Correct Answer: B

Rationale: The correct answer is B: Ototoxic. Ototoxic refers to substances that are harmful to the ear, potentially causing hearing loss or damage. The prefix "oto-" specifically relates to the ear. Otoplasty (A) is a surgical procedure to reshape the ear, not related to toxicity. Otalgia (C) refers to ear pain, not toxicity. Tinnitus (D) is a symptom of ringing in the ears, not directly related to toxicity. Therefore, the term "ototoxic" is the best indicator of a substance being toxic to the ear due to its specific reference to ear toxicity.

Correct Answer: A

Rationale: The correct answer is A: Avoiding using soap on the irradiated areas. Soap can irritate the skin and exacerbate the risk for impaired skin integrity in a client receiving radiation therapy. By avoiding soap, we minimize the risk of skin breakdown and promote skin healing. B: Applying talcum powder can actually worsen skin irritation and should be avoided. C: Wearing a lead apron is not relevant to the nursing diagnosis of risk for impaired skin integrity. D: Removing thoracic skin markings is not necessary for skin integrity and may disrupt the treatment plan.

Correct Answer: D

Rationale: The correct answer is D: Stop the infusion. This is the best action because the client is likely experiencing a transfusion reaction. Stopping the infusion immediately is crucial to prevent further complications. Reporting the signs and symptoms to the healthcare provider (A) can cause a delay in addressing the reaction. While monitoring vital signs (B) and assessing respiratory status (C) are important, stopping the infusion takes precedence to ensure the client's safety and prevent a severe reaction.

Correct Answer: D

Rationale: The correct answer is D, a behavior change. Urinary retention in older adults with a neurologic deficit can manifest as a behavior change, such as increased agitation, confusion, or restlessness due to discomfort from the inability to empty the bladder. Amnesia (A) is memory loss and not directly related to urinary retention. Hypertension (B) and hypotension (C) are related to blood pressure regulation and are not specific signs of urinary retention. In contrast, a behavior change (D) is a common and characteristic sign indicating urinary retention in this population.
