The client has a resting heart rate of 80 and a regular rhythm. What is the likely source of electrical activity in this client?

  • A. The sino-atrial node
  • B. The atrio-ventricular node
  • C. The Purkinje fibers
  • D. The bundle of HIS
Correct Answer: A

Rationale: The correct answer is A: The sino-atrial node. The SA node is the natural pacemaker of the heart, responsible for initiating the electrical impulses that regulate the heartbeat. A resting heart rate of 80 with a regular rhythm indicates normal sinus rhythm, which is typically driven by the SA node. The SA node is located in the right atrium and generates electrical impulses that spread through the atria, causing them to contract.

Choice B (The atrio-ventricular node) is incorrect because the AV node serves to delay the electrical impulse to allow the atria to contract before the ventricles. Choice C (The Purkinje fibers) is incorrect as they are responsible for rapid conduction of the electrical impulse to the ventricles. Choice D (The bundle of HIS) is incorrect as it is part of the electrical conduction system that transmits the impulse from the AV node to the bundle branches.

A toddler requires supplemental oxygen therapy for a cyanotic heart defect. In planning for home care, the nurse would discuss which of the following with the parents?

  • A. The need to maintain the child on bedrest.
  • B. Means of promoting mobility while meeting the need for supplemental oxygen.
  • C. Symptoms of oxygen toxicity.
  • D. How to draw blood for blood gases.
Correct Answer: B

Rationale: The correct answer is B because promoting mobility while meeting the need for supplemental oxygen is crucial for the toddler's development and overall well-being. Bedrest (A) is not recommended for a toddler unless medically necessary. Discussing symptoms of oxygen toxicity (C) is important but not the priority in this case. Drawing blood for blood gases (D) is a medical procedure that should be performed by healthcare professionals, not parents. Prioritizing mobility and oxygen therapy helps maintain the child's physical health and supports their growth and development.

Which of the following is a nursing intervention to ensure that the client is free from injury caused by falls?

  • A. Nurse monitors for chest pain and elevated LDL levels.
  • B. Nurse monitors for swelling and heaviness of legs.
  • C. Nurse monitors postural changes in BP.
  • D. Nurse monitors temperature for mild fever.
Correct Answer: C

Rationale: Monitoring postural BP changes helps identify orthostatic hypotension, reducing fall risk.

In preparing George Gates for a cardiac catheterization, you would

  • A. Encourage him to report any discomfort or strange feelings during the procedure
  • B. Send a urine specimen for culture and sensitivity
  • C. Shave his abdomen
  • D. Tell him there is nothing to worry about
Correct Answer: A

Rationale: Reporting sensations aids in detecting complications.

When caring for a patient with acute coronary syndrome who has returned to the coronary care unit after having angioplasty with stent placement, the nurse obtains the following assessment data. Which data indicate the need for immediate action by the nurse?

  • A. Heart rate 102 beats/min
  • B. Pedal pulses 1+ bilaterally
  • C. Report of severe chest pain
  • D. Blood pressure 103/54 mm Hg
Correct Answer: C

Rationale: The correct answer is C. Severe chest pain in a patient with acute coronary syndrome post-angioplasty indicates a potential complication like stent thrombosis or re-occlusion. Immediate action is needed to assess and manage. A: Heart rate 102 bpm may be expected post-procedure. B: Pedal pulses 1+ bilaterally may indicate decreased perfusion but not an immediate threat. D: Blood pressure 103/54 mm Hg may be low but not an immediate concern unless symptomatic.

When caring for a patient with acute coronary syndrome who has returned to the coronary care unit after having angioplasty with stent placement, the nurse obtains the following assessment data. Which data indicate the need for immediate action by the nurse?

  • A. Heart rate 102 beats/min
  • B. Pedal pulses 1+ bilaterally
  • C. Report of severe chest pain
  • D. Blood pressure 103/54 mm Hg
Correct Answer: C

Rationale: The correct answer is C: Report of severe chest pain. Severe chest pain in a patient with acute coronary syndrome after angioplasty with stent placement can indicate a potential complication like stent thrombosis or myocardial infarction. Immediate action is required to assess the patient's condition, administer appropriate interventions, and prevent further complications.

A: Heart rate 102 beats/min - Although an elevated heart rate can indicate cardiac stress, it is not as urgent as severe chest pain in this context.
B: Pedal pulses 1+ bilaterally - While decreased pedal pulses may indicate peripheral vascular issues, it is not as critical as addressing severe chest pain in a patient with acute coronary syndrome.
D: Blood pressure 103/54 mm Hg - Although low blood pressure can be concerning, it is not as immediately life-threatening as severe chest pain in this scenario.
