What is a condition where the heart muscle is weakened and unable to pump blood effectively, often leading to heart failure?
- A. Cardiomyopathy
- B. Myocarditis
- C. Endocarditis
- D. Pericarditis
Correct Answer: A
Rationale: The correct answer is A: Cardiomyopathy. Cardiomyopathy refers to a condition where the heart muscle is weakened and unable to pump blood effectively, leading to heart failure. This is because the heart muscle becomes enlarged, thickened, or stiff, affecting its ability to pump blood efficiently.
Incorrect choices:
B: Myocarditis - Myocarditis is inflammation of the heart muscle, not necessarily associated with weakening of the heart muscle leading to heart failure.
C: Endocarditis - Endocarditis is inflammation of the inner lining of the heart chambers and valves, not directly related to the weakening of the heart muscle.
D: Pericarditis - Pericarditis is inflammation of the pericardium (the outer lining of the heart), and does not directly involve the weakening of the heart muscle.
Which surgical procedure involves removing a portion of the lung?
- A. Lobectomy
- B. Pneumonectomy
- C. Tracheostomy
- D. Bronchoscopy
Correct Answer: A
Rationale: The correct answer is A: Lobectomy. A lobectomy involves the removal of a lobe of the lung. This procedure is commonly done to treat lung cancer or other conditions affecting a specific lobe. Pneumonectomy (B) involves the removal of an entire lung, not just a portion. Tracheostomy (C) is the surgical creation of an opening in the windpipe to help with breathing, not a lung removal procedure. Bronchoscopy (D) is a diagnostic procedure to visualize the airways using a flexible tube with a camera, not a lung removal surgery. Therefore, A is the correct choice for removing a portion of the lung.
Which heart chamber receives oxygenated blood from the four pulmonary veins and serves as a reservoir during ventricular systole?
- A. Right atrium
- B. Left atrium
- C. Right ventricle
- D. Left ventricle
Correct Answer: B
Rationale: The correct answer is B: Left atrium. The left atrium receives oxygenated blood from the pulmonary veins, acting as a reservoir during ventricular systole. This blood is then pumped into the left ventricle for distribution to the body. The right atrium receives deoxygenated blood from the body via the vena cavae. The right ventricle pumps this blood to the lungs for oxygenation. The left ventricle is responsible for pumping oxygenated blood to the rest of the body. Therefore, the left atrium is the correct choice based on its role in receiving oxygenated blood from the pulmonary veins.

The healthcare provider is monitoring a client receiving lidocaine IV. What side effect is the healthcare provider most concerned about?
- A. Severe headache
- B. Nausea and vomiting
- C. Seizures
- D. Tremors
Correct Answer: C
Rationale: The correct answer is C: Seizures. Lidocaine is a local anesthetic that can cause central nervous system toxicity, leading to seizures. This is the most concerning side effect because it can be life-threatening. Severe headache (A) is not typically associated with lidocaine toxicity. Nausea and vomiting (B) are common side effects but not the most concerning. Tremors (D) can occur but are not as serious as seizures in this context.
