Question 1 of 9

Which part of the body requires a continuous supply of oxygen and vital nutrients to support life and death?

Correct Answer: C

Rationale: The brain requires a continuous supply of oxygen and vital nutrients to support life and prevent death. Oxygen and nutrients are essential for brain function, and any interruption in the supply can lead to serious consequences, including brain damage or death. Therefore, ensuring a constant flow of oxygen and nutrients to the brain is vital for survival and overall health.

Question 2 of 9

Why has an ACE inhibitor been prescribed following an MI?

Correct Answer: B

Rationale: Following a myocardial infarction (MI), ACE inhibitors are commonly prescribed due to their proven benefit in reducing mortality and improving outcomes post-MI. These medications help by decreasing the workload of the heart, preventing remodeling of the heart chambers, and improving survival rates. While ACE inhibitors may have effects on potassium levels, the primary reason for their prescription post-MI is their mortality-reducing properties.

Question 3 of 9

A client taking nitroglycerin (Nitrostat) for angina asks the nurse to explain possible side effects. What should NOT be included in client teaching?

Correct Answer: C

Rationale: Hyponatremia is not a common side effect associated with nitroglycerin use. Nitroglycerin typically causes side effects such as reflex tachycardia, dizziness, and hypotension due to its vasodilatory effects. Therefore, it is important for the nurse to educate the client about these potential side effects to promote understanding and appropriate management.

Question 4 of 9

Which part of the body requires a continuous supply of oxygen and vital nutrients to support life and death?

Correct Answer: C

Rationale: The brain requires a continuous supply of oxygen and vital nutrients to support life and prevent death. Oxygen and nutrients are essential for brain function, and any interruption in the supply can lead to serious consequences, including brain damage or death. Therefore, ensuring a constant flow of oxygen and nutrients to the brain is vital for survival and overall health.

Question 5 of 9

A client has been prescribed diltiazem (Cardizem) and asks the nurse what type of drug this is. Which response by the nurse is most appropriate?

Correct Answer: D

Rationale: Diltiazem (Cardizem) belongs to the class of drugs known as calcium channel blockers. These medications work by blocking calcium from entering the muscle cells of the heart and blood vessels, leading to relaxation of the blood vessels and reduced workload on the heart. This helps in lowering blood pressure and improving blood flow. It is crucial for the nurse to provide accurate information to the client about the type of drug prescribed to ensure understanding and compliance with the treatment plan.

Question 6 of 9

A client has ordered a thrombolytic medication for the treatment of CVA. Which type of stroke should not be treated with a thrombolytic?

Correct Answer: A

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Question 7 of 9

The nurse is caring for a client who has chronic angina. Treatment for the condition has been unsuccessful. Which medication does the nurse anticipate will be prescribed?

Correct Answer: D

Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.

Question 8 of 9

The client with angina is being discharged to home. The nurse is instructing the client on dietary changes. What should be included in this teaching?

Correct Answer: A

Rationale: The correct answer is to decrease salt and fat intake and limit alcohol intake. These dietary changes can help manage angina by reducing the workload on the heart and preventing further plaque buildup in the arteries. Choices B, C, and D are incorrect as dietary restrictions for angina typically involve reducing salt, fat, and alcohol intake, rather than increasing sugar or cholesterol intake.

Question 9 of 9

A client taking nitroglycerin (Nitrostat) complains of a headache. Which conclusion is most appropriate by the nurse?

Correct Answer: D

Rationale: Nitroglycerin is known to cause headaches as a common side effect due to its vasodilatory properties. It dilates blood vessels, which can lead to headaches. While a headache can indicate other serious conditions, the most common association with nitroglycerin use is a headache. It is crucial for the nurse to recognize this side effect and provide appropriate education and support to the client.
