Correct Answer: D

Rationale: The correct answer is D: Lymphocyte. Lymphocytes are a type of white blood cell that play a crucial role in adaptive immunity. They include T cells and B cells, which are responsible for recognizing and attacking specific pathogens. T cells help regulate the immune response and directly attack infected cells, while B cells produce antibodies to target pathogens. Neutrophils (
A), monocytes (
B), and basophils (
C) are important for innate immunity, not adaptive immunity. Neutrophils are phagocytic cells that engulf and destroy pathogens, monocytes differentiate into macrophages to engulf pathogens, and basophils are involved in allergic reactions.
Therefore, the correct answer is D because lymphocytes are key players in adaptive immunity.

Correct Answer: B

Rationale: The correct answer is B: Clients with metal implants in their body. An MRI uses strong magnetic fields, which can interact with metal implants, causing movement or heating of the metal and potential harm to the client. This could lead to serious injuries or complications during the scan. Overweight clients (choice
A), clients over the age of 60 (choice
C), and clients with brain tumors (choice
D) do not have contraindications for an MRI scan.

Correct Answer: B

Rationale: The correct answer is B: Ask the patient to describe the type of reaction. First, the nurse needs to assess the severity of the latex allergy to determine the appropriate interventions. Understanding the type of reaction can help guide treatment and prevent future exposure. Isolating the patient (choice
A) is not necessary unless there is a severe reaction. Terminating the interview (choice
C) prematurely is not appropriate as crucial information may be missed. Documenting the allergy (choice
D) is important but not as urgent as assessing the reaction type.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Malignant melanoma, basal cell epithelioma, and squamous cell carcinoma are all forms of skin cancer associated with prolonged sun exposure. Melanoma is the deadliest form, originating in melanocytes; basal cell and squamous cell carcinomas are more common but less aggressive. All three types can develop due to cumulative UV radiation exposure.
Therefore, all options are correct in this context.

Correct Answer: A

Rationale: The correct answer is A: Disturbed thought processes. This is the problem statement because it identifies the specific nursing diagnosis that reflects the client's cognitive impairment. "Disturbed thought processes" directly addresses the issue the nurse is observing in the client. The other choices are not the problem statement. "Related to" is the etiology or cause of the problem, "Alzheimer’s disease" is the medical condition, and "Incoherent language" is the defining characteristic or evidence of the problem.
Therefore, A is the correct answer as it clearly states the client's primary issue.
