NUR 213 Health Exam

The best response by the nurse is:

b. "I'm glad to hear you are sleeping well now."

Why this is correct:

This response acknowledges the client’s improved sleep, which is essential for recovery after a myocardial infarction (MI). Rest is critical for healing, reducing stress, and supporting heart health. By validating the client’s statement in a nonjudgmental way, the nurse creates an open and supportive environment for further discussion.

Why the other options are incorrect:

• a. "Do you have any concerns about sexuality?"
  
  
  
  
  • While concerns about intimacy are common after an MI, the client has not explicitly mentioned it. Bringing it up without context could make the client uncomfortable or defensive.
  
  
  
  


• c. "Sleep near your spouse in case of emergency."
  
  
  
  • The client’s comfort and rest take priority over being physically close to someone. Unless the client has a medical condition that requires close monitoring, this advice is unnecessary.
  
  
  
  


• d. "Why would you move into the guest room?"
  
  
  
  • This question could sound judgmental or intrusive. The client may feel the need to justify their decision instead of discussing their actual concerns.
  
  
  
  

Summary:

The correct response (b) is supportive and affirming, encouraging the client to share more details if they choose. The other options either assume too much, sound judgmental, or are not focused on the client’s stated concern.

Correct Answer: A) Confusion

Why It Is Correct:

In the compensatory stage of shock, the body attempts to maintain perfusion to vital organs despite decreased tissue perfusion. One of the key signs of this stage is altered mental status, such as confusion, restlessness, or anxiety, due to decreased oxygen delivery to the brain. The sympathetic nervous system activates, leading to vasoconstriction, tachycardia, and increased respiratory rate in an attempt to compensate for reduced cardiac output.

Why the Other Choices Are Incorrect:

Anuria

Incorrect because Anuria (absence of urine output) is a sign of severe renal failure, which occurs in the progressive or irreversible (refractory) stage of shock, rather than the compensatory stage. In the compensatory stage, urine output may decrease (oliguria) but does not typically stop completely.

Petechiae

Incorrect because Petechiae (small pinpoint hemorrhages) suggest disseminated intravascular coagulation (DIC), which is associated with severe septic or late-stage shock rather than the compensatory stage. At this stage, coagulation abnormalities are not yet prominent.

Blood pressure 84/50 mm Hg

Incorrect because In the compensatory stage, the body maintains blood pressure through vasoconstriction and increased heart rate. A BP of 84/50 mm Hg suggests progressive shock, where compensatory mechanisms begin to fail. In early compensatory shock, BP may still be normal or slightly decreased, but the pulse pressure (difference between systolic and diastolic pressure) narrows.

Summary:

Correct Answer: Confusion, because decreased cerebral perfusion leads to altered mental status.

Anuria occurs in the progressive or irreversible stage.

Petechiae are associated with DIC, seen in late-stage shock.

Blood pressure of 84/50 mm Hg suggests progression beyond the compensatory stage.

Recognizing the compensatory stage of shock is critical for early intervention to prevent deterioration into progressive or irreversible shock.

Correct Answer:

B Pantoprazole

Explanation:

Pantoprazole is a proton pump inhibitor (PPI), a class of medications that reduce stomach acid production by blocking the H+/K+ ATPase enzyme in gastric parietal cells. PPIs are commonly prescribed for peptic ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome to promote healing and prevent ulcer recurrence.

Why the Other Options Are Incorrect:

1. Cimetidine – This is an H2 receptor antagonist (H2RA), not a PPI. It works by blocking histamine receptors in the stomach to reduce acid production but is less potent than PPIs.


2. Ranitidine – Another H2 receptor antagonist, previously used for acid suppression but withdrawn from many markets due to safety concerns related to contamination with NDMA, a probable carcinogen.


3. Famotidine – Also an H2 receptor antagonist, which can reduce acid production but is not as effective as PPIs in treating peptic ulcers.

Summary:

The nurse should anticipate the provider ordering Pantoprazole, as it is a proton pump inhibitor (PPI) and is more effective than H2 receptor antagonists in reducing stomach acid and promoting ulcer healing.

The correct answer is: b. A 50-year-old who is post coronary artery bypass graft (CABG) surgery.

Why is this correct?

Atrial fibrillation (AFib) is a common complication after coronary artery bypass graft (CABG) surgery. This is due to:

Postoperative inflammation and stress on the heart.

Changes in atrial conduction caused by surgical manipulation of the heart.

Electrolyte imbalances and sympathetic nervous system activation during recovery.

Studies show that 20-40% of patients develop AFib after cardiac surgery, typically within the first 2-4 days postoperatively. This makes the post-CABG patient the highest-risk individual in this scenario.

Why are the other options incorrect?

a. A 45-year-old who takes an aspirin daily:

Aspirin is not a risk factor for AFib. This client has no other identifiable risk factors (e.g., hypertension, heart disease, or advanced age). While aspirin is often used for cardiovascular protection, it does not contribute to the development of AFib.

c. A 78-year-old who had a carotid endarterectomy:

Advanced age (78 years) is a risk factor for AFib, but carotid endarterectomy (surgery to remove plaque from the carotid artery) is not directly associated with AFib. The procedure does not involve the heart or atria, so it does not significantly increase the risk of AFib.

d. An 80-year-old with chronic obstructive pulmonary disease (COPD):

While COPD can increase the risk of AFib due to chronic hypoxia, pulmonary hypertension, and right heart strain, the risk is not as high as in a post-CABG patient. Advanced age (80 years) is a risk factor, but the absence of cardiac surgery makes this client less likely to develop AFib compared to the post-CABG patient.

Summary:

The post-CABG patient is at the greatest risk for atrial fibrillation due to the high incidence of AFib following cardiac surgery. The other clients either lack significant risk factors (aspirin use) or have conditions that pose a lower risk (carotid endarterectomy, COPD) compared to the post-CABG patient. Nurses should closely monitor post-CABG patients for signs of AFib, such as irregular heart rate, palpitations, or hemodynamic instability, especially in the first few days after surgery.

Correct Answer: A. "Minimize or abstain from caffeine."

Why it is Correct

Caffeine is a common trigger for premature atrial contractions (PACs), as it stimulates the heart and can increase the frequency of ectopic beats. Educating the client to minimize or avoid caffeine (found in coffee, tea, energy drinks, and chocolate) helps reduce the occurrence of PACs and associated palpitations. Other lifestyle modifications, such as reducing stress, avoiding alcohol, and getting adequate rest, can also help prevent PAC episodes.

Why the Other Options Are Incorrect

B. "Lie on your side until the attack subsides."

Changing position does not prevent or stop PACs, as they are caused by ectopic electrical impulses in the atria. Lying on the side may temporarily alter heart sensations but does not address the underlying cause.

C. "Use your oxygen when you experience PACs."

Oxygen is not a standard treatment for PACs unless the client has an underlying hypoxemic condition (e.g., COPD or heart failure). PACs in an otherwise healthy person do not require oxygen therapy.

D. "Take amiodarone (Cordarone) daily to prevent PACs."

Amiodarone is a potent antiarrhythmic used for serious arrhythmias like atrial fibrillation or ventricular tachycardia, not for occasional PACs. Unnecessary use of amiodarone exposes the patient to significant side effects, including thyroid dysfunction, pulmonary toxicity, and liver damage.

Summary

The best teaching point is to "Minimize or abstain from caffeine," as caffeine can trigger PACs and palpitations. The other options (lying on the side, using oxygen, or taking amiodarone) are not appropriate interventions for occasional, self-resolving PACs

Correct Answer: The client took warfarin 2.5 mg with a sip of water at 6 a.m.

Explanation:

Warfarin is an anticoagulant that increases the risk of excessive bleeding during surgery. Patients undergoing major surgeries, such as total hip replacement, are typically instructed to discontinue warfarin several days before surgery to allow clotting factors to normalize. If the patient took warfarin on the day of surgery, the surgeon must be notified immediately to assess bleeding risk and decide whether to delay the procedure or administer reversal agents like vitamin K or fresh frozen plasma.

Why the Other Choices Are Incorrect:

The client took half their morning dose of insulin at 6 a.m.

Patients with diabetes often require adjusted insulin regimens before surgery to prevent hypoglycemia or hyperglycemia during fasting. Taking a half dose is a common preoperative adjustment, so this would not be an emergency requiring immediate surgeon notification.

The client took metoprolol 25 mg with a sip of water at 6 a.m.

Beta-blockers like metoprolol are usually continued before surgery to prevent rebound hypertension and tachycardia. Taking metoprolol is expected and does not require notifying the surgeon.

The client took phenytoin 100 mg with a sip of water at 6 a.m

Phenytoin (Dilantin) is an antiseizure medication that must be taken consistently to prevent seizures. Surgeons often allow essential medications like anticonvulsants with a small sip of water before surgery, so this would not require immediate notification.

Summary:

The nurse should immediately collaborate with the surgeon if a patient took warfarin before surgery due to the high risk of bleeding. Other medications, such as insulin, beta-blockers, and anticonvulsants, are often continued or adjusted preoperatively and do not require urgent intervention.

Correct Answer:  (a) "Would you like to talk more about this?"

Explanation:

The client's statement suggests emotional distress and potential suicidal ideation. The nurse’s priority is to assess the client’s feelings further and provide emotional support. By offering an open-ended question, the nurse encourages the client to express their emotions, allowing for a more comprehensive psychosocial assessment.

Why the Other Options Are Wrong:

(b) "You are lucky to have such a devoted daughter."

This dismisses the client’s distress and does not address their emotional concerns.

(c) "It is normal to feel as though you are a burden."

This may invalidate the client’s feelings and reinforce their negative thoughts, potentially worsening their distress.

(d) "Would you like to meet with the chaplain?"

While spiritual support may be helpful, it is not the first priority. The nurse should first explore the client’s feelings and assess for suicidal ideation.

Summary:

The nurse should actively listen and encourage the client to express their thoughts, making option (a) the best choice. If the client shows signs of suicidal intent, further intervention, such as involving a mental health professional, would be necessary.

Correct Answer:

D. Sinus rhythm with premature ventricular contractions (PVCs).

Why It Is Correct

PVCs occur when an ectopic ventricular focus fires early, producing a wide and bizarre QRS complex that is not preceded by a P wave. The underlying rhythm remains a normal sinus rhythm, but the premature beats disrupt its regularity. Key characteristics of PVCs on ECG include:

• Wide QRS complexes (≥0.12 seconds) occurring prematurely.


• No preceding P wave before the PVC.


• Compensatory pause after the PVC.


• Underlying normal sinus rhythm.

PVCs can be isolated or appear in patterns such as:

• Bigeminy (PVC every other beat).


• Trigeminy (PVC every third beat).


• Couplets (two consecutive PVCs).

While occasional PVCs are usually benign, frequent or consecutive PVCs can indicate ventricular irritability, electrolyte imbalances, or ischemia and may require further evaluation.

Why the Other Options Are Incorrect

• A. Ventricular Tachycardia (VT)
  
  
  
  
  • Incorrect because:
    
    
    
    
    • VT consists of three or more consecutive PVCs at a rapid rate (100-250 bpm).
    
    
    • There is no normal sinus rhythm; instead, there are continuous wide QRS complexes.
    
    
    • If the ECG strip shows a normal rhythm with occasional PVCs, then VT is not the correct answer.
    
    
    
    
  
  
  
  


• B. Ventricular Fibrillation (VF)
  
  
  
  • Incorrect because:
    
    
    
    • VF is a chaotic, irregular rhythm with no identifiable P waves, QRS complexes, or T waves.
    
    
    • There is no organized electrical activity—just disorganized fibrillatory waves.
    
    
    • If there is an underlying sinus rhythm, VF cannot be the correct answer.
    
    
    
    
  
  
  
  


• C. Sinus Rhythm with Premature Atrial Contractions (PACs)
  
  
  
  • Incorrect because:
    
    
    
    • PACs originate from the atria, so they have an early P wave with a normal QRS complex.
    
    
    • PACs do not cause wide QRS complexes—which is the hallmark of PVCs.
    
    
    • If the premature beats are wide and bizarre, then PVCs, not PACs, are present.
    
    
    
    
  
  
  
  

Summary

The best answer is D: Sinus rhythm with premature ventricular contractions (PVCs) because the ECG likely shows a normal sinus rhythm with occasional wide, premature QRS complexes. The other options—VT, VF, and PACs—describe different ECG patterns that do not match the description of PVCs in a sinus rhythm.

Correct Answer: b. Give the client an aspirin.

Explanation:

The Joint Commission's Core Measures for Acute Myocardial Infarction (AMI) focus on evidence-based interventions that improve patient outcomes. Early administration of aspirin is a key component because aspirin inhibits platelet aggregation, reducing further clot formation and limiting myocardial damage. Administering chewable aspirin (160–325 mg) immediately upon arrival is a priority intervention in suspected MI cases.

Why the other options are incorrect:

a. "Obtain an electrocardiogram (ECG) now and in the morning."

An immediate ECG is essential to confirm the MI and guide treatment. However, this is not the best action to meet The Joint Commission’s Core Measures compared to aspirin administration.

c. "Notify the Rapid Response Team."

While calling for help is necessary if the patient is unstable, the Rapid Response Team is typically used for inpatient emergencies before a cardiac arrest occurs. In an ER setting, an MI protocol is already in place, making this not the priority action.

d. "Prepare to administer thrombolytics."

Thrombolytics (e.g., tissue plasminogen activator, t-PA) are used in ST-elevation myocardial infarction (STEMI) when PCI is unavailable. However, the first-line intervention is aspirin, and thrombolytic therapy depends on ECG findings and eligibility criteria (e.g., no contraindications such as recent surgery or bleeding risk).

Summary:

The best initial action to meet The Joint Commission’s Core Measures for AMI is to administer aspirin immediately to reduce clot progression and improve outcomes.
