Question 1 of 5
A nurse is monitoring a client who is on telemetry. Which of the following findings on the ECG strip should the nurse recognize as normal sinus rhythm?
Correct Answer: D
Rationale: The correct answer is D: The P wave falls before the QRS complex. In a normal sinus rhythm, the P wave should precede the QRS complex, indicating that the electrical impulse originates in the sinoatrial (S
A) node and travels through the atria before reaching the ventricles. This sequence signifies a coordinated electrical conduction through the heart, ensuring efficient and effective pumping.
Choices A, B, and C are incorrect as they describe abnormalities in the ECG readings that are not indicative of normal sinus rhythm.
Choice A suggests a prolonged PR interval, choice B indicates T wave inversion which can be a sign of cardiac ischemia or electrolyte imbalance, and choice C implies a widened QRS complex which may indicate conduction abnormalities.
Therefore, the correct interpretation of a normal sinus rhythm on ECG is when the P wave falls before the QRS complex.
Question 2 of 5
What are the anticipated signs and symptoms for a client who has meningitis? (Select all that apply.)
Correct Answer: B,C,D,E
Rationale: The correct signs and symptoms for meningitis include fever and chills due to systemic infection, nuchal rigidity from meningeal irritation, severe headache from increased intracranial pressure, and Brudzinski's sign, which indicates meningeal irritation when the neck is flexed. Bradycardia is not a typical sign of meningitis. The summary of why the other choices are incorrect is that they do not align with the classic signs and symptoms of meningitis, which are mainly related to systemic infection and meningeal irritation.
Question 3 of 5
A nurse is caring for a client who is experiencing hypovolemic shock. Which of the following blood products should the nurse anticipate administering to this client?
Correct Answer: B
Rationale: The correct answer is B: Packed RBCs. In hypovolemic shock, there is a significant loss of blood volume leading to decreased oxygen-carrying capacity. Packed RBCs are the most appropriate choice as they directly increase the oxygen-carrying capacity of the blood, helping to improve tissue perfusion and oxygenation. Cryoprecipitates (
A) are used to manage bleeding disorders, not hypovolemic shock. Albumin (
C) is a colloid solution used for volume expansion but does not directly address the decreased oxygen-carrying capacity in hypovolemic shock. Platelets (
D) are used for clotting disorders, not for hypovolemic shock.
Question 4 of 5
A client is experiencing decorticate posturing. Which assessment finding would the nurse expect to observe in this client?
Correct Answer: A
Rationale: The correct answer is A: Flexion and internal rotation of upper extremities. Decorticate posturing is characterized by the arms flexing inward towards the core of the body with internal rotation. This occurs due to damage to the corticospinal tracts. Other choices are incorrect because decerebrate posturing (extension and external rotation of upper extremities) is associated with damage to the brainstem. Extension and internal rotation (
Choice
C) and external rotation (
Choice
D) are not typical findings in decorticate posturing.
Question 5 of 5
A nurse in an urgent care center is assessing a client who reports a sudden onset of irregular palpitations, fatigue, and dizziness. The nurse finds a rapid and irregular heart rate with a significant pulse deficit. Which of the following dysrhythmias should the nurse expect to find on the ECG?
Correct Answer: A
Rationale: The correct answer is A: Atrial fibrillation. Atrial fibrillation is characterized by an irregular and rapid heartbeat, which aligns with the client's symptoms of irregular palpitations and rapid heart rate with a significant pulse deficit. Atrial fibrillation can result in decreased cardiac output leading to fatigue and dizziness. Sinus bradycardia (
B) and sinus tachycardia (
C) do not match the description of a rapid and irregular heart rate with a pulse deficit. First-degree AV block (
D) is characterized by a delay in conduction between the atria and ventricles, which would not cause the rapid heart rate and pulse deficit observed in this case.
