Nursing Elites

1. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

2. A 35-year-old female client has just been admitted to the post-anesthesia recovery unit following a partial thyroidectomy. Which statement reflects the nurse's accurate understanding of the expected outcome for the client following this surgery?

• A. Supplemental hormonal therapy will probably be unnecessary.
• B. The thyroid will regenerate to a normal size within a few years.
• C. The client will be restricted from eating seafood.
• D. The remainder of the thyroid will be removed at a later date.

Correct answer: C

Rationale: After a partial thyroidectomy, the client may be advised to avoid eating seafood due to its high iodine content, which can affect the thyroid function. Choice A is incorrect because after a partial thyroidectomy, supplemental hormonal therapy may be necessary. Choice B is incorrect as the thyroid does not regenerate after a partial thyroidectomy. Choice D is incorrect; the remaining portion of the thyroid is not typically removed at a later date unless there are specific medical reasons to do so.

3. A male client notifies the nurse that he feels short of breath and has chest pressure radiating down his left arm. A STAT 12-lead electrocardiogram (ECG) is obtained and shows ST segment elevation in leads II, III, aVF, and V4R. The nurse collects blood samples and gives a normal saline bolus. What action is most important for the nurse to implement?

• A. Obtain the results for STAT serum cardiac biomarkers.
• B. Assess for contraindications for thrombolytic therapy.
• C. Measure ST-segment height and waveform changes.
• D. Transfer for percutaneous coronary intervention (PCI).

Correct answer: B

Rationale: Assessing for contraindications for thrombolytic therapy is crucial as it determines whether the client is a candidate for reperfusion therapy. In this scenario, the client is presenting with symptoms and ECG changes consistent with an acute myocardial infarction (MI). Thrombolytic therapy aims at restoring blood flow to the heart muscle, reducing the size of the infarct. However, it is essential to assess for contraindications such as recent surgery, active bleeding, or a history of stroke to avoid potential complications. Obtaining serum cardiac biomarkers or measuring ST-segment changes are important steps in the diagnosis of MI but are not as time-sensitive as assessing for contraindications to thrombolytic therapy. Transfer for percutaneous coronary intervention (PCI) is a definitive treatment for MI, but assessing for thrombolytic therapy eligibility takes precedence in this acute situation.

4. The nurse is caring for a client with end-stage renal disease (ESRD) who is scheduled for hemodialysis. Which clinical finding is most concerning?

• A. Blood pressure of 110/70 mmHg
• B. Heart rate of 110 beats per minute
• C. Fever of 100.4°F
• D. Respiratory rate of 24 breaths per minute

Correct answer: C

Rationale: The correct answer is C. A fever of 100.4°F is most concerning in a client with ESRD scheduled for hemodialysis because it may indicate an underlying infection that requires immediate attention. Elevated body temperature can be a sign of systemic infection, which can quickly worsen in individuals with compromised renal function. Monitoring for infection is crucial in ESRD patients to prevent complications. Choices A, B, and D are not as immediately concerning in this context. While variations in blood pressure, heart rate, and respiratory rate should be monitored, they are not as indicative of a potentially severe issue as an unexplained fever in this scenario.

5. The nurse teaches an adolescent male client how to use a metered dose inhaler. What instruction should the nurse provide?

• A. Secure the mouthpiece under the tongue.
• B. Press down on the device after breathing in fully.
• C. Move the device one to two inches away from the mouth.
• D. Breathe out slowly and deeply while compressing the device.

Correct answer: C

Rationale: The correct instruction for using a metered dose inhaler is to move the device one to two inches away from the mouth. This distance helps ensure effective delivery of the medication directly to the airways. Choice A is incorrect as the mouthpiece should be placed between the lips, not under the tongue. Choice B is incorrect because the device should be pressed down before breathing in, not after. Choice D is wrong because the patient should breathe out fully before using the inhaler, not while compressing the device.
