Nokea
The client on amiodarone develops pulmonary fibrosis. What action should the nurse take?
- A. Notify the healthcare provider immediately.
- B. Continue the medication and monitor lung function.
- C. Discontinue the medication and start oxygen therapy.
- D. Reduce the dose and monitor respiratory status.
Correct Answer: A
Rationale: Step-by-step rationale:
1. Pulmonary fibrosis is a serious side effect of amiodarone.
2. Immediate notification of the healthcare provider is necessary to address this potentially life-threatening complication.
3. The healthcare provider will need to evaluate the client's condition, consider alternative treatments, and adjust the care plan accordingly.
Summary of incorrect choices:
B. Continuing the medication without intervention can worsen the pulmonary fibrosis.
C. Discontinuing the medication is necessary, but oxygen therapy alone may not address the underlying issue.
D. Reducing the dose may not be sufficient to manage the pulmonary fibrosis and delaying provider notification can lead to further complications.

What condition is characterized by narrowed or blocked arteries in the legs or arms, leading to pain and mobility issues?
- A. Peripheral artery disease
- B. Atherosclerosis
- C. Raynaud's disease
- D. Varicose veins
Correct Answer: A
Rationale: The correct answer is A: Peripheral artery disease (PAD). PAD is characterized by narrowed or blocked arteries in the legs or arms, leading to pain and mobility issues due to reduced blood flow. Atherosclerosis refers to the buildup of plaque in arteries but doesn't specify limbs. Raynaud's disease is a condition affecting blood supply to extremities due to cold or stress, not arterial blockages. Varicose veins involve enlarged, twisted veins, not arterial blockages. Therefore, the correct choice is A as it specifically addresses the narrowed or blocked arteries in limbs causing pain and mobility issues.
Which of the following nursing interventions should a nurse perform when caring for a client with congestive heart failure who has decreased cardiac output?
- A. Encourage activities that engage the Valsalva maneuver.
- B. Encourage the client to perform exercises.
- C. Assess apical heart rate before administering digitalis.
- D. Offer small, frequent feedings.
Correct Answer: C
Rationale: Digitalis therapy requires careful monitoring of heart rate to prevent toxicity and worsening cardiac output.
High SVR is most likely to cause damage to which organ?
- A. Brain
- B. Heart
- C. Retina
- D. Kidney
Correct Answer: D
Rationale: Elevated SVR strains renal arterioles, leading to kidney damage.
What is the ability of cardiac cells to generate an electrical impulse without being stimulated by an external source?
- A. Automaticity
- B. Contractility
- C. Conductivity
- D. Refractoriness
Correct Answer: A
Rationale: Automaticity is the ability of cardiac cells to generate an electrical impulse spontaneously without external stimulation. It is a fundamental property of specialized cardiac cells like pacemaker cells. Contractility refers to the ability of muscle cells to contract in response to an electrical stimulus. Conductivity is the ability of cardiac cells to transmit electrical impulses. Refractoriness is the period during which cardiac cells are unable to respond to a new stimulus. Therefore, in this context, the correct answer is A: Automaticity.
What is a surgical procedure to redirect blood flow around a blocked or narrowed artery, often involving the use of a graft from another part of the body?
- A. Coronary artery bypass graft (CABG)
- B. Valve replacement
- C. Aneurysm repair
- D. Atherectomy
Correct Answer: A
Rationale: The correct answer is A: Coronary artery bypass graft (CABG). This procedure is used to redirect blood flow around a blocked or narrowed artery by creating a bypass using a graft from another part of the body. Step 1: The blocked or narrowed artery is identified through diagnostic tests. Step 2: A graft, often taken from the chest, leg, or arm, is used to create a new pathway for blood to flow around the blockage. Step 3: This helps improve blood flow to the heart muscle, relieving symptoms such as chest pain and reducing the risk of a heart attack. Summary: B (Valve replacement) involves replacing a damaged heart valve, C (Aneurysm repair) deals with treating a weakened area in a blood vessel, and D (Atherectomy) is a procedure to remove plaque from arteries, none of which match the description provided.
