1. A client has a new prescription for Cyanocobalamin (Vitamin B12) injections. Which of the following client statements indicates an understanding of the teaching?

Correct answer: A

Rationale: The correct answer is A. Clients with pernicious anemia or other causes of vitamin B12 deficiency may need to take cyanocobalamin for life to prevent deficiency. It is a lifelong treatment in many cases to maintain adequate B12 levels. Choice B is incorrect because stopping the medication when symptoms improve may lead to a relapse of the deficiency. Choice C is incorrect as cyanocobalamin injections are usually administered on an empty stomach. Choice D is incorrect as there is no need to avoid green, leafy vegetables while taking cyanocobalamin; in fact, these vegetables are good dietary sources of vitamin B12.

2. What are the common manifestations of a thrombotic stroke?

Correct answer: A

Rationale: The correct answer is A: Gradual loss of function on one side of the body. A thrombotic stroke is characterized by a gradual onset of symptoms due to interrupted blood flow in the brain. This interruption results in manifestations such as weakness, numbness, or paralysis on one side of the body. Choices B, C, and D are incorrect because sudden loss of consciousness, severe headache, confusion, seizures, and convulsions are more commonly associated with conditions other than thrombotic strokes.

3. Which condition involves the heart muscle becoming abnormally thickened, reducing its ability to pump blood?

Correct answer: A

Rationale: The correct answer is A: Hypertrophic cardiomyopathy. In this condition, the heart muscle thickens, leading to a decreased ability to pump blood effectively. Choice B, Dilated cardiomyopathy, is characterized by the heart chambers enlarging and weakening. Choice C, Restrictive cardiomyopathy, involves the heart muscle becoming rigid and less compliant. Choice D, Ischemic cardiomyopathy, is when the heart muscle is weakened due to reduced blood flow.

4. The muscular system is responsible for body movements, maintenance of posture, and production of body heat.

Correct answer: A

Rationale: The correct answer is A: True. The muscular system is indeed responsible for body movements, maintenance of posture, and the production of body heat. Muscles contract and relax to allow movement, help in maintaining an upright posture, and generate heat through muscle activity. Choice B is incorrect because the functions mentioned are accurate. Choice C is incorrect as the functions of the muscular system are well-established. Choice D is incorrect as there is a correct answer among the options.

5. Which immunoglobulin presents the first challenge to the antigen?

Correct answer: C

Rationale: IgM is the first immunoglobulin to challenge the antigen during an immune response. IgM is the primary antibody produced during the initial or primary immune response. It is efficient in agglutination and complement activation, making it crucial in the early stages of defense. IgA is mainly found in mucosal areas and secretions. IgG is the most abundant antibody in circulation and is involved in secondary immune responses. IgE is primarily associated with allergic reactions and parasitic infections. Therefore, IgM is the correct choice as it acts first during the immune response, while the other immunoglobulins have different roles and functions.
