1. What is a condition where the heart muscle becomes thickened without an obvious cause, leading to a reduction in the heart's ability to pump blood?

• A. Hypertrophic cardiomyopathy
• B. Dilated cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Myocarditis

Correct answer: A

Rationale: Hypertrophic cardiomyopathy is the correct answer. It is a condition characterized by the abnormal thickening of the heart muscle without an obvious cause, which impairs the heart's ability to effectively pump blood. Dilated cardiomyopathy (choice B) involves the enlargement and weakening of the heart chambers, not thickening. Restrictive cardiomyopathy (choice C) refers to the stiffening of the heart muscle, limiting its ability to fill properly. Myocarditis (choice D) is inflammation of the heart muscle usually caused by a viral infection, not thickening.

2. Which term refers to the contraction phase of the heart when blood is ejected from the chambers?

• A. Systole
• B. Diastole
• C. Contractility
• D. Afterload

Correct answer: A

Rationale: The correct answer is A, systole. Systole is the phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. During diastole (choice B), the heart relaxes and fills with blood, contrasting with systole. Contractility (choice C) refers to the ability of the heart to contract effectively. Afterload (choice D) is the pressure the heart must work against to eject blood during systole.

3. The client is prescribed warfarin. What should the client be taught about this medication?

• A. Avoid foods high in vitamin K.
• B. Take the medication with food to prevent stomach upset.
• C. Take the medication at the same time every day.
• D. Increase the dose if a dose is missed.

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is an anticoagulant medication, and vitamin K can counteract its effects. Therefore, it is important for clients taking warfarin to avoid foods high in vitamin K to maintain the medication's effectiveness. Choice B is incorrect because warfarin should be taken consistently as prescribed, regardless of food intake. Choice C is incorrect because while consistency in timing is important, it is not specific to the effectiveness of warfarin. Choice D is incorrect because clients should never increase the dose of warfarin on their own, especially to make up for a missed dose, as it can lead to serious bleeding risks.

4. Which condition is characterized by the lungs becoming scarred and stiff, leading to difficulty breathing and inadequate oxygen intake into the bloodstream?

• A. Pulmonary fibrosis
• B. Cystic fibrosis
• C. COPD
• D. Tuberculosis

Correct answer: A

Rationale: The correct answer is A, Pulmonary fibrosis. Pulmonary fibrosis is a lung disease where lung tissue is damaged and scarred, resulting in breathing difficulties and decreased oxygen transfer into the bloodstream. Cystic fibrosis (B) is a genetic disorder primarily affecting the lungs and digestive system, not causing lung scarring. COPD (C) includes conditions like chronic bronchitis and emphysema but doesn't specifically involve lung scarring. Tuberculosis (D) is a bacterial infection that primarily affects the lungs but doesn't cause lung tissue scarring and stiffness as seen in pulmonary fibrosis.

5. What term describes a condition where a person experiences difficulty breathing when lying flat and requires multiple pillows to sleep comfortably?

• A. Orthopnea
• B. Dyspnea
• C. Tachypnea
• D. Bradypnea

Correct answer: A

Rationale: The correct answer is A, Orthopnea. Orthopnea is a condition where a person finds it hard to breathe while lying flat and needs to use multiple pillows to sleep comfortably. This position helps relieve the discomfort by allowing better lung expansion. Choice B, Dyspnea, refers to difficulty breathing in general, not specifically related to lying flat. Choice C, Tachypnea, is rapid breathing and is not directly related to difficulty breathing while lying down. Choice D, Bradypnea, is slow breathing and does not describe the condition of having trouble breathing when lying flat.
