Correct Answer: B

Rationale: In a situation where Anginal pain persists after taking one sublingual tablet and waiting 5 minutes, it is crucial to call emergency services (911) immediately. This could indicate a myocardial infarction (heart attack) rather than a typical Anginal attack. The client can take a second sublingual tablet while waiting for emergency assistance. If the pain persists after taking the second tablet, a third tablet can be taken after an additional 5 minutes. Prompt action is essential in such situations to ensure appropriate and timely medical intervention.

Correct Answer: B

Rationale: The correct answer is to avoid foods high in vitamin K. Vitamin K can interfere with the effectiveness of Warfarin by counteracting its anticoagulant effects. Foods high in vitamin K, such as leafy green vegetables, should be limited in the diet of individuals taking Warfarin to maintain a consistent level of the medication's effectiveness.

Correct Answer: A

Rationale: Propranolol is a non-selective beta-blocker that can cause bronchoconstriction, making it contraindicated for clients with asthma. Asthma is a contraindication for Propranolol due to the potential of worsening bronchoconstriction and causing respiratory distress in individuals with this condition.

Correct Answer: B

Rationale: The healthcare professional should withhold the medication and notify the provider of the client's previous reaction to penicillin. This information is crucial for the provider to prescribe an alternative antibiotic. Allergic reactions to penicillin can range from mild to severe anaphylaxis, so prior sensitization should be reported to the provider to avoid potential adverse reactions.

Correct Answer: C

Rationale: Methylnaltrexone is an opioid antagonist used to treat severe constipation unrelieved by laxatives in opioid-dependent clients. It blocks the mu opioid receptors in the GI tract, helping to alleviate constipation without affecting pain relief or causing withdrawal symptoms.
