Question 1 of 5
What is the expected outcome for Valproate?
Correct Answer: D
Rationale: Valproate is an anticonvulsant medication commonly used to treat seizure disorders such as epilepsy. It works by stabilizing electrical activity in the brain, which helps to reduce the occurrence of seizures. Therefore, the expected outcome of Valproate treatment is a decrease in seizure activity and an improvement in seizure control.
Question 2 of 5
A 6-year-old boy cuts his hand on the training wheel of his bicycle. The wound is 1.5 cm in size and the bleeding stops with direct pressure. One of the steps of blood clotting involved platelet aggregation through activation of collagen. Platelet release of granules is mediated by the release of mediators. Which of the following mediators, if activated, will likely cause bleeding to continue?
Correct Answer: C
Rationale: Platelet aggregation stops bleeding, but serotonin is correct-if defective, bleeding persists. ADP , Thrombin , and Thromboxane A2 (E) promote clotting. Dopamine is unrelated. Serotonin's vasoconstrictive role, if impaired, could prolong bleeding, though less critical than others here.
Question 3 of 5
The nurse is preparing to administer an injection to a preschool-age child. Which approaches are appropriate for this age group? (Select all that apply.)
Correct Answer: D
Rationale: Preschool-age children benefit from brief, concrete explanations about medical procedures, as they have limited understanding of abstract concepts. Encouraging participation, such as allowing the child to choose a bandage or hold a toy, can reduce anxiety and increase cooperation. Providing comfort measures, such as praise or a small reward, after the injection helps reinforce positive behavior. While magical thinking is characteristic of this age group, it is not an appropriate strategy for explaining medical procedures. Therefore, the nurse should focus on concrete explanations, participation, and comfort measures.
Question 4 of 5
An important function of calcium is to
Correct Answer: D
Rationale: Calcium regulates nerve transmission-e.g., neurotransmitter release, per physiology-not acid-base (HCO3-), glucose (insulin), or energy (ATP). Nerve function is key, per role.
Question 5 of 5
The nurse works with a physician who frequently prescribes benzodiazepines. The use of benzodiazepines in which patient would cause the nurse the most concern?
Correct Answer: A
Rationale: Benzos (e.g., diazepam) in an 87-year-old with a cane raise fall risk-sedation and slow clearance heighten injury odds, per geriatrics. Kids rarely get benzos-alternatives exist. Adults (42, 32) handle them better unless dependent. Elderly frailty drives concern, a safety red flag.
