1. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)

• A. Age
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: D

Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.

2. Which of the following measures would be appropriate for a nurse to teach the parent of a nine-month-old infant about diaper dermatitis?

• A. Use only cloth diapers that are rinsed in bleach
• B. Do not use occlusive ointments on the rash
• C. Use commercial baby wipes with each diaper change
• D. Discontinue a new food that was added to the infant's diet just prior to the rash

Correct answer: D

Rationale: Diaper dermatitis can be caused by various factors, one of which includes introducing new foods to the infant's diet. Discontinuing the new food that was added just before the rash can help identify and eliminate the potential cause. Options A and C are not directly related to addressing the cause of diaper dermatitis. While using cloth diapers rinsed in bleach may be a preventive measure for diaper dermatitis, it is not addressing a specific cause. Option B, advising against using occlusive ointments on the rash, may actually be beneficial in managing diaper dermatitis, but it does not address the cause of the condition.

3. How does shock typically progress?

• A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
• B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
• C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
• D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

4. A two-year-old child has sustained an injury to the leg and refuses to walk. The nurse in the emergency department documents swelling of the lower affected leg. Which of the following does the nurse suspect is the cause of the child's symptoms?

• A. Possible fracture of the tibia.
• B. Bruising of the gastrocnemius muscle.
• C. Possible fracture of the radius.
• D. No anatomic injury, the child wants his mother to carry him.

Correct answer: A

Rationale: The child's refusal to walk, along with swelling of the lower leg, indicates a possible fracture, specifically of the tibia. Fractures can cause pain and swelling, leading to difficulty or refusal to bear weight on the affected limb. Choice B, bruising of the gastrocnemius muscle, would not typically result in the child refusing to walk. Choice C, a possible fracture of the radius, is less likely given the location of the swelling and the associated refusal to walk. Choice D, stating no anatomic injury and attributing the child's behavior to wanting to be carried by the mother, is incorrect as the physical findings suggest a potential fracture that needs to be evaluated further.

5. The nurse is caring for a patient who has recently had a successful catheter ablation. Which assessment finding demonstrates a successful outcome of this procedure?

• A. The patient is free of electrolyte imbalances
• B. The patient's WBC count is within normal limits
• C. The patient's EKG reading is regular
• D. The patient's urine output is 45 mL/hour

Correct answer: C

Rationale: A successful outcome of a catheter ablation procedure for arrhythmias, particularly SVT, is indicated by a regular EKG reading. Catheter ablation involves the use of radiofrequency energy to destroy the conduction fiber in the heart responsible for the arrhythmia. This destruction helps in preventing further episodes of arrhythmia. While choices A, B, and D are important assessments in patient care, they are not specific indicators of the success of a catheter ablation procedure. Electrolyte imbalances, WBC count, and urine output can be affected by various factors and are not directly related to the effectiveness of a catheter ablation in treating arrhythmias.
