Correct Answer: B

Rationale: When a client with multiple sclerosis is receiving intravenous methylprednisolone, the nurse's priority action is to monitor for signs of infection. Corticosteroids like methylprednisolone can suppress the immune system, increasing the risk of infection. Monitoring for signs of infection allows for early detection and prompt intervention. Monitoring blood glucose levels may be important in clients receiving corticosteroids for prolonged periods, but it is not the priority in this case. Encouraging increased oral fluid intake is generally beneficial but not the priority over monitoring for infection. Checking the client's temperature is important but not the priority action compared to monitoring for signs of infection.

Correct Answer: B

Rationale: Increased sensitivity to cold and dry skin may indicate that the dosage of levothyroxine is too low, requiring adjustment. This symptom is typical of hypothyroidism when the body's metabolism slows down, leading to feeling cold and having dry skin. Choices A, C, and D present symptoms more commonly associated with hyperthyroidism, where the body is in a state of overactivity, leading to weight loss, increased heart rate, and sweating. Therefore, these symptoms would not indicate the need for dosage adjustment in a client with hypothyroidism.

Correct Answer: A

Rationale: The nurse's signature on a surgical consent form signifies that the client voluntarily grants permission for the procedure to be done. This is the correct answer because the nurse's signature does not imply the client's competence, understanding of risks and benefits, or that the client signed the form freely and voluntarily. The nurse's role is to verify that the client has made an informed decision and is providing consent for the procedure.

Correct Answer: C

Rationale: Engaging the child in blowing out the penlight simulates play and can reduce fear, helping with cooperation during the assessment. Choice A is not recommended as it may increase anxiety by separating the child from the parent. Choice B is not appropriate as it involves playing with a syringe, which may not be safe or suitable. Choice D is not ideal for a 4-year-old child as understanding organ functions may be beyond their developmental level.

Correct Answer: B

Rationale: An adolescent expressing 'life without purpose' after taking duloxetine (Cymbalta) may be indicating suicidal ideation, which requires immediate attention. The initial period of antidepressant treatment can increase the risk of suicidal thoughts, especially in younger populations. Increased appetite (Choice A) is a common side effect of duloxetine and may not require immediate follow-up. Mood swings (Choice C) and insomnia (Choice D) are also possible side effects of the medication but are not as urgent as addressing suicidal ideation.
