Nursing Elites

1. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

2. When counting a client's radial pulse, the nurse notes the pulse is weak and irregular. To record the most accurate heart rate, what should the nurse do?

• A. Recheck the radial pulse in thirty minutes
• B. Palpate the radial pulse for thirty seconds and double the rate
• C. Count the apical pulse rate for sixty seconds
• D. Compare the radial pulse rate bilaterally and record the higher rate

Correct answer: C

Rationale: The correct answer is to count the apical pulse rate for sixty seconds. The apical pulse is more accurate, especially when peripheral pulses are weak or irregular. Counting the apical pulse for a full minute provides a more precise heart rate measurement. Option A is incorrect because waiting for thirty minutes is unnecessary and could delay potential interventions. Option B is incorrect because doubling the radial pulse rate may not provide an accurate representation of the heart rate. Option D is incorrect because comparing radial pulses bilaterally does not give the most accurate heart rate measurement; the apical pulse is preferred in this situation.

3. The nurse is preparing to administer an intramuscular injection to a 6-month-old infant. Which site is most appropriate for this injection?

• A. Deltoid muscle
• B. Ventrogluteal muscle
• C. Dorsogluteal muscle
• D. Vastus lateralis muscle

Correct answer: D

Rationale: The vastus lateralis muscle is the preferred site for intramuscular injections in infants due to its size and safety. The deltoid muscle is typically used for adults and older children. The ventrogluteal muscle is more commonly used in toddlers and older children. The dorsogluteal muscle is not recommended for intramuscular injections in any age group due to its proximity to major nerves and blood vessels, which poses a risk of injury or sciatic nerve damage.

4. The nurse is caring for a client with a tracheostomy who is on mechanical ventilation. What is the priority nursing intervention?

• A. Suction the tracheostomy as needed
• B. Ensure the tracheostomy ties are secure
• C. Provide humidified oxygen
• D. Clean any exudate around the tracheostomy site

Correct answer: A

Rationale: The priority nursing intervention for a client with a tracheostomy on mechanical ventilation is to suction the tracheostomy as needed. Suctioning is essential to maintain a clear airway and prevent respiratory distress. While ensuring tracheostomy ties are secure (choice B) is important, it is not as urgent as airway maintenance. Providing humidified oxygen (choice C) is beneficial but does not address the immediate need for airway clearance. Cleaning exudate around the tracheostomy site (choice D) is important for hygiene but takes precedence over ensuring airway patency through suctioning.

5. During a routine prenatal visit, a nurse measures a client’s fundal height at 26 weeks gestation. What should the fundal height be?

• A. Approximately 26 cm
• B. Between 24 to 28 cm
• C. Above the umbilicus by two finger widths
• D. Below the xiphoid process

Correct answer: B

Rationale: The correct answer is B: 'Between 24 to 28 cm.' Fundal height is expected to be approximately equal to the weeks of gestation, so at 26 weeks, the fundal height should typically range between 24 to 28 cm. Choice A is incorrect because fundal height is not an exact measurement of gestational age in centimeters. Choice C is incorrect as it provides a general description above the umbilicus, which is not specific to 26 weeks gestation. Choice D is incorrect as the fundal height would not reach below the xiphoid process at 26 weeks gestation.
