Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. Following an emergency Cesarean delivery, the nurse encourages the new mother to breastfeed her newborn. The client asks why she should breastfeed now. Which information should the nurse provide?

• A. To bond with the baby.
• B. To help the baby latch on better.
• C. To stimulate contraction of the uterus.
• D. To promote milk production.

Correct answer: C

Rationale: The correct answer is C: 'To stimulate contraction of the uterus.' After delivery, breastfeeding helps in stimulating the release of oxytocin, which triggers the contraction of the uterus. This contraction is crucial to prevent uterine hemorrhage and facilitate the involution process. Choices A, B, and D are incorrect. While breastfeeding can indeed help in bonding with the baby and promoting milk production, in the immediate postpartum period after a Cesarean section, the priority is to ensure uterine contraction to prevent complications.

3. A client with a history of asthma is admitted with shortness of breath. Which finding requires immediate intervention?

• A. Increased respiratory rate.
• B. Absence of breath sounds.
• C. Expiratory wheezes.
• D. Productive cough with green sputum.

Correct answer: B

Rationale: The correct answer is B: Absence of breath sounds. This finding can indicate a pneumothorax or severe asthma exacerbation, both of which require immediate intervention to ensure adequate ventilation and prevent further complications. Increased respiratory rate (choice A) is common in asthma exacerbations but may not always necessitate immediate intervention. Expiratory wheezes (choice C) are typical in asthma and may not always indicate a critical condition. A productive cough with green sputum (choice D) suggests a possible respiratory infection but does not warrant immediate intervention as much as the absence of breath sounds.

4. The nurse is assisting with the triage of clients at a large community disaster and finds a man lying on the ground, who states that the blast threw him out of a second-story window. Which action should the nurse implement first?

• A. Logroll the client to his side and assess for back injuries
• B. Perform a complete neurological assessment
• C. Open the client's airway immediately
• D. Place the nurse's hands around the client's neck to stabilize

Correct answer: C

Rationale: Opening the client's airway immediately is the priority in this scenario. Ensuring the airway is clear takes precedence over other actions as it is crucial for the client's breathing and oxygenation. Logrolling the client to assess for back injuries may worsen the condition if there are spinal injuries, so this should not be done as the first step. Performing a complete neurological assessment is important but not the immediate priority over ensuring the airway is clear. Placing the nurse's hands around the client's neck to stabilize is incorrect and could potentially harm the client, as neck stabilization should only be done if there is a suspected neck injury, which is not indicated in this case.

5. A home health nurse is reviewing the laboratory results for several clients with heart failure. Which client finding would the nurse report to the health care provider immediately?

• A. Total cholesterol 190
• B. Glycosylated hemoglobin of 7%
• C. B-type natriuretic peptide 550 pg/ml (more than 100 is concerning)
• D. Potassium 3.7

Correct answer: C

Rationale: An elevated B-type natriuretic peptide level indicates worsening heart failure, requiring immediate attention. This biomarker reflects the severity of heart failure and helps guide treatment decisions. Total cholesterol and glycosylated hemoglobin are important for assessing cardiovascular risk and diabetes management but are not indicative of acute heart failure exacerbation. A potassium level of 3.7 falls within the normal range and does not suggest an immediate concern in the context of heart failure.
