Correct Answer: D

Rationale: The correct answer is D. Epinephrine, when applied locally, constricts blood vessels, reducing blood flow and slowing down bleeding. This vasoconstrictive effect helps control nosebleeds effectively. Choice A is incorrect because although epinephrine can raise blood pressure, it is not the primary mechanism for treating nosebleeds. Choice B is incorrect as epinephrine's bronchodilation effect is not relevant in this context. Choice C is incorrect as while promoting blood clotting is beneficial, epinephrine primarily acts by vasoconstriction to control bleeding.

Correct Answer: D

Rationale: The correct answer is D: absence seizures. Barbiturate anticonvulsants are not effective in treating absence seizures because they can worsen this type of seizure by suppressing brain activity. Barbiturates are typically used to treat tonic-clonic seizures and partial seizures, but not absence seizures. Febrile seizures are typically managed without barbiturate anticonvulsants. In summary, barbiturate anticonvulsants are effective in treating partial seizures and tonic-clonic seizures, but not absence seizures or febrile seizures due to their mechanisms of action and potential side effects.

Correct Answer: A

Rationale: The correct answer is A because in the four-point gait with partial weight bearing, the client should move the right crutch ahead first to provide support and stability, followed by the left foot. This sequence ensures proper weight distribution and balance. Moving both crutches together (B) may compromise stability. Moving the left crutch and right foot together (C) may cause uneven weight distribution. Moving both crutches and weaker leg together (D) may not provide adequate support for the weaker leg.

Correct Answer: D

Rationale: The correct answer is D because the nurse's signature indicates that they verified the patient's signature on the consent form. This step ensures that the patient has signed the document willingly. Choice A is incorrect because the nurse doesn't obtain informed consent, that's the responsibility of the physician. Choice B is incorrect because nurses do not provide informed consent. Choice C is incorrect as the nurse witnessing the signature doesn't imply they answered all surgical procedure questions.

Correct Answer: B

Rationale: The correct answer is B: Health behavior. Evaluating the patient's demonstration of self-injection assesses their ability to perform a specific health-related action. This choice focuses on the patient's actions and behaviors related to their health, aligning with the scenario provided. Choice A: Health status is incorrect because it refers to the patient's current physical condition, not their ability to perform a specific health action. Choice C: Psychological self-control is incorrect as it pertains to the patient's ability to regulate their emotions and impulses, not their ability to self-administer injections. Choice D: Health service utilization is incorrect as it relates to the frequency and pattern of healthcare services used by the patient, not their ability to perform a specific health behavior.
