Nursing Elites

1. Which of the following is not a cause of tachycardia?

• A. Fever
• B. Exercise
• C. Sympathetic nervous system stimulation
• D. Parasympathetic nervous system stimulation

Correct answer: D

Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.

2. A client in labor is receiving oxytocin. Which of the following findings indicates that the nurse should increase the rate of infusion?

• A. Urine output of 20 ml/hr.
• B. Montevideo units constantly at 300 mm Hg.
• C. FHR pattern showing absent variability.
• D. Contractions occurring every 5 minutes and lasting 30 seconds.

Correct answer: B

Rationale: Montevideo units measure the strength and frequency of contractions during labor. A consistent Montevideo units reading of 300 mm Hg or higher is indicative of effective uterine contractions. In this scenario, an increase in the rate of oxytocin infusion may be warranted to further augment contractions and promote progress in labor. The other options, such as low urine output, absent variability in fetal heart rate, and short contractions, do not directly correlate with the need for an increase in oxytocin infusion rate.

3. What is the best description of resonance?

• A. Sounds created by air-filled structures
• B. Short, high-pitched, and thudding
• C. Moderately loud with a musical quality
• D. Drum-like

Correct answer: A

Rationale: Resonance refers to the quality of sound produced by vibrations that are reinforced by other vibrations of the same frequency. In the context of the human body, resonance is often associated with sounds produced by air-filled structures like the lungs, vocal cords, and resonating cavities. Therefore, the best description of resonance from the given options is 'Sounds created by air-filled structures.' This choice aligns with the concept of resonance as it relates to sound production in the human body. Choices B, C, and D are incorrect as they do not specifically relate to the concept of resonance or its association with air-filled structures.

4. A healthcare professional is reviewing laboratory data for a client who has chronic kidney disease. Which of the following findings should the healthcare professional expect?

• A. Increased creatinine.
• B. Increased hemoglobin.
• C. Increased bicarbonate.
• D. Increased calcium.

Correct answer: A

Rationale: In chronic kidney disease, the kidneys are unable to effectively filter waste products from the blood, leading to an accumulation of creatinine. Creatinine levels are commonly elevated in individuals with impaired kidney function, making it a key indicator of kidney health. Therefore, an increased creatinine level would be an expected finding in a client with chronic kidney disease.

5. A client in the emergency department is experiencing an acute asthma attack. Which assessment indicates an improvement in respiratory status?

• A. SaO2 95%
• B. Wheezing
• C. Retraction of sternal muscles
• D. Premature ventricular complexes (PVC's)

Correct answer: A

Rationale: An SaO2 of 95% indicates an improvement in the client's oxygen saturation, suggesting better respiratory status. In asthma exacerbation, a decrease in SaO2 levels would signal worsening respiratory distress. Wheezing, retraction of sternal muscles, and premature ventricular complexes are indicators of respiratory compromise and worsening respiratory status in acute asthma attacks. Monitoring SaO2 levels is crucial in assessing the effectiveness of interventions and guiding treatment decisions.
