A male client with a gunshot wound requires an emergency blood transfusion. His blood type is AB negative. Which blood type would be the safest for him to receive?

Correct Answer: C

Rationale: The correct answer is C: A Rh-negative. The rationale is that the client with AB negative blood type can receive blood from donors with blood type A or B, as well as Rh-negative blood to avoid any immune reactions. Choice A is incorrect because it is Rh-positive, which can lead to a hemolytic reaction. Choice B is incorrect because it is Rh-positive, which is not compatible with AB negative blood type. Choice D is incorrect because it is O, which is not compatible with AB blood type. Therefore, choice C is the safest option for the client to receive a blood transfusion without any adverse reactions.

Correct Answer: C

Rationale: The correct answer is C: Kidneys' excretion of sodium and water. When the kidneys excrete sodium and water, the blood volume decreases, leading to a drop in blood pressure. Excretion of excess sodium helps to reduce fluid retention, which can contribute to hypertension. Retention of sodium and water (B) would increase blood volume and blood pressure. Excretion of sodium only (A) would not address the issue of fluid retention. Retention of sodium and excretion of water (D) would not effectively reduce blood volume and lower blood pressure.

Correct Answer: A

Rationale: The correct answer is A because providing the wife with the number of a crisis center offers immediate help and support in a dangerous situation. This step is crucial in ensuring her safety and connecting her with professionals trained to assist in abusive situations. Choice B is incorrect as leaving an abusive partner can be a complex and dangerous process that requires careful planning and support. Choice C is incorrect as discussing the situation with family may not always be safe or helpful, as they may not understand the seriousness of the abuse or may inadvertently put the wife at risk. Choice D is incorrect as it places blame on the victim rather than addressing the abuser's behavior and providing practical support.

Correct Answer: D

Rationale: Correct Answer: D - Serious violations of age-related norms Rationale: 1. Conduct disorder involves persistent patterns of behavior that violate social norms. 2. Children with conduct disorder often exhibit aggression, deceitfulness, and rule-breaking behaviors. 3. These behaviors are serious violations of age-related norms for typical child development. 4. The other choices are not characteristic of conduct disorder; distractibility, ritualistic behaviors, and preference for inanimate objects are more commonly associated with other disorders such as ADHD, OCD, and autism, respectively.

Correct Answer: B

Rationale: The correct answer is B: Tolerance. Tolerance refers to the need for increased amounts of a substance to achieve the desired effect over time. In this case, the patient's increased intake of alcohol to achieve the same effect indicates tolerance. Withdrawal (A) involves symptoms that occur when the substance is reduced or stopped. Intoxication (C) refers to the immediate effects of a substance on the body. Psychological dependence (D) involves a strong desire or craving for the substance, which is not explicitly indicated in the scenario.
