If a patient's blood pressure is 150/96, what is his pulse pressure?
- A. 54
- B. 96
- C. 150
- D. 246
Correct Answer: A
Rationale: Pulse pressure is calculated by subtracting the diastolic pressure from the systolic pressure. In this case, the systolic pressure is 150 and the diastolic pressure is 96. Therefore, the pulse pressure is 150 - 96 = 54. Pulse pressure represents the force generated by the heart with each contraction and is an important indicator of cardiovascular health.
To assess the kidney function of a patient with an indwelling urinary (Foley) catheter, the nurse measures the hourly urine output. When should she notify the physician?
- A. Less than 30 ml/hour
- B. 64 ml in 2 hours
- C. 90 ml in 3 hours
- D. 125 ml in 4 hours
Correct Answer: A
Rationale: Notifying the physician is necessary when the urine output is less than 30 ml/hour as it indicates impaired kidney function. Adequate urine output is essential for monitoring kidney function, and a urine output less than 30 ml/hour could suggest potential renal issues that require medical attention.
Which of the following patients is at greatest risk for developing pressure ulcers?
- A. An alert chronic arthritic patient treated with steroids and aspirin
- B. An 88-year-old incontinent patient with gastric cancer who is confined to bed at home
- C. An apathetic 63-year-old COPD patient receiving nasal oxygen via cannula
- D. A confused 78-year-old patient with congestive heart failure (CHF) who requires assistance to get out of bed
Correct Answer: B
Rationale: The correct answer is B. An elderly patient who is incontinent, bedridden, and suffering from a serious illness like gastric cancer is at the highest risk for developing pressure ulcers. Being bedridden and incontinent increases the pressure on certain areas of the body, leading to tissue damage and the development of pressure ulcers. Additionally, the patient's age and underlying health condition further contribute to their risk. It is crucial to identify and address such risk factors promptly to prevent the occurrence of pressure ulcers in vulnerable patients.
A healthcare provider reaches to answer the telephone on a busy pediatric unit, momentarily turning away from a 3-month-old infant she has been weighing. The infant falls off the scale, suffering a skull fracture. The healthcare provider could be charged with:
- A. Defamation
- B. Assault
- C. Battery
- D. Malpractice
Correct Answer: D
Rationale: The scenario described involves a breach of duty by the healthcare provider to properly supervise the infant, resulting in harm. This failure to meet the standard of care falls under the category of malpractice, which refers to professional negligence or misconduct. Malpractice specifically applies to situations where a healthcare provider's actions or omissions deviate from the accepted standard of care, causing harm to a patient. In this case, the nurse's lack of supervision leading to the infant falling off the scale and sustaining a skull fracture would be considered malpractice.
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.
