HESI 799 RN Exit Exam Capstone

Correct Answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

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.

Correct Answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

Correct Answer: D

Rationale: The correct answer is D: 'It reduces gastrointestinal upset.' Levodopa/carbidopa can cause nausea and other gastrointestinal side effects. Taking the medication with food can help reduce these side effects and improve the client's comfort. Choices A, B, and C are incorrect because taking the medication with food does not primarily enhance effectiveness, improve absorption, or prevent orthostatic hypotension. The main reason for advising to take the medication with meals is to minimize gastrointestinal upset.

Correct Answer: A

Rationale: Injections over 1 mL should be split into two separate injections for young children. This helps in preventing discomfort, ensuring proper absorption, and reducing the risk of tissue damage. Giving the medication in one injection of 2.0 ml might be too much for a 2-year-old child. Choices B and D are incorrect because the dorsal gluteal site is not recommended for children due to potential injury, and changing the form of medication might not be necessary if the volume can be adjusted. Choice C is unnecessary as splitting the dose into two injections is the appropriate action.
