Convert from Fahrenheit to Celsius: 98.6
Correct Answer: 37
Rationale: Solution: (98.6 - 32) × 5/9 = 37°C. Answer: 37°C.
Question 2 of 5
The nurse is caring for a patient who is being discharged from the hospital after being treated for hypertension. The patient is instructed to take blood pressure 3 times a day and to keep a record of the readings. The nurse recommends that the patient purchase a portable electronic blood pressure device. Which other information will the nurse share with the patient?
Correct Answer: D
Rationale: You will need to recalibrate the machine: Electronic blood pressure devices require periodic recalibration to maintain accuracy. The patient should follow the manufacturer’s guidelines for recalibration and compare readings with a manual blood pressure check at clinic visits. You will need to use a stethoscope properly: A portable electronic blood pressure device is automatic and does not require the use of a stethoscope. The device detects oscillations in arterial pressure to provide a reading. You can move your arm during the reading: Movement during the reading can interfere with accuracy and produce incorrect results. The patient should keep the arm still and at heart level. You can apply the cuff in any manner: The cuff must be applied correctly—snug but not too tight, with the lower edge about 1 inch above the antecubital fossa, and the bladder of the cuff positioned over the artery—to ensure accurate readings.
Question 3 of 5
A nurse is providing discharge teaching to a client who has asthma and new prescriptions for cromolyn and albuterol, both by nebulizer. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: C
Rationale: I will be sure to take the albuterol before taking the cromolyn': Albuterol (a bronchodilator) should be taken first to open the airways, allowing better absorption of cromolyn (an anti-inflammatory medication). 'I will administer the medications 10 minutes apart': Timing is important, but this option does not specify which medication should be taken first. The correct sequence is albuterol first, followed by cromolyn. 'I will use both medications immediately after exercising': Cromolyn is a mast cell stabilizer used for prevention, not acute symptoms. It should be taken 15-30 minutes before exercise to prevent exercise-induced bronchospasm, not after. 'If my breathing begins to feel tight, I will use the cromolyn immediately': Cromolyn is not a rescue medication. Albuterol should be used for acute bronchospasm, while cromolyn is for long-term asthma control.
Question 4 of 5
A nurse is caring for a patient with a wound. Which assessment data will be most relevant with regard to wound healing?
Correct Answer: D
Rationale: Pulse oximetry assessment: Oxygenation is a critical factor in wound healing. Low oxygen levels impair tissue repair, increase infection risk, and slow cell regeneration. Pulse oximetry assesses the oxygen levels in the blood, making it the most relevant assessment for wound healing. Muscular strength assessment: While muscular strength is important for overall mobility and health, it is not a key factor in wound healing. Wound healing is primarily influenced by oxygenation, perfusion, and nutrition. Sensation assessment: While sensation is important in patients with conditions like diabetes (due to the risk of neuropathy and unnoticed wounds), it is not the most relevant assessment for determining wound healing. Sleep assessment: Adequate rest is beneficial for healing, but sleep assessment is not the primary factor that determines wound healing. Other physiological factors play a greater role.
Question 5 of 5
A patient has been diagnosed with heart failure and cardiac output is decreased. Which formula can the nurse use to calculate cardiac output?
Correct Answer: C
Rationale: Stroke volume × heart rate: Cardiac Output (CO) = Stroke Volume (SV) × Heart Rate (HR). Stroke volume is the amount of blood pumped per beat, and heart rate is the number of beats per minute. Multiplying these values gives the total volume of blood pumped per minute, making this the correct formula. Myocardial contractility × myocardial blood flow: While myocardial contractility and blood flow affect cardiac output, they are not part of the formula for calculating it. Ventricular filling time/diastolic filling time: This ratio does not determine cardiac output. While diastolic filling time affects stroke volume, it is not the standard formula for cardiac output. Preload/afterload: Preload and afterload influence cardiac function but are not used to directly calculate cardiac output.
