Nursing Elites

1. When assessing the force or strength of a pulse, what would the nurse recall about the pulse?

• A. Is a reflection of the heart's stroke volume
• B. Typically recorded on a 0- to 3-point scale
• C. Demonstrates elasticity of the blood vessel wall
• D. Reflects the blood volume in the arteries during diastole

Correct answer: A

Rationale: When assessing the force or strength of a pulse, the nurse should recall that it is a reflection of the heart's stroke volume. The heart pumps an amount of blood (the stroke volume) into the aorta, causing arterial walls to flare and generate a pressure wave felt as the pulse in the periphery. The force of the pulse is typically recorded on a 0- to 3-point scale, not a 0- to 2-point scale. The force of the pulse does not demonstrate the elasticity of blood vessel walls or reflect the blood volume in the arteries during diastole. Therefore, choices B, C, and D are incorrect.

2. Which of the following statements best describes footdrop?

• A. The foot is permanently fixed in the dorsiflexion position
• B. The foot is permanently fixed in the plantar flexion position
• C. The toes of the foot are permanently fanned
• D. The heel of the foot is permanently rotated outward

Correct answer: B

Rationale: Footdrop results in the foot becoming permanently fixed in a plantar flexion position, not dorsiflexion. This position points the toes downward. The client may be unable to put weight on the foot, making ambulation difficult. Footdrop can be caused by immobility or chronic illnesses that cause muscle changes, such as multiple sclerosis or Parkinson's disease. Choice A is incorrect because footdrop leads to plantar flexion, not dorsiflexion. Choice C is incorrect as it describes a different condition known as 'toe fanning.' Choice D is incorrect as it describes an external rotation of the heel, which is not a characteristic of footdrop.

3. The nurse is assessing the vital signs of a 3-year-old patient who appears to have an irregular respiratory pattern. How would the nurse assess this child's respirations?

• A. Respirations should be counted for 1 full minute.
• B. Child's pulse and respirations should be simultaneously checked for 30 seconds and then multiplied by 2.
• C. Child's respirations should be checked for a minimum of 5 minutes to identify any variations in his or her respiratory pattern.
• D. Patient's respirations should be counted for 15 seconds and then multiplied by 4.

Correct answer: A

Rationale: To accurately assess a child's respiratory pattern, the nurse should count respirations for a full minute. This duration provides a comprehensive view of the child's breathing pattern, ensuring abnormalities are not missed. Counting for only 30 seconds may not capture irregularities effectively. Checking respirations for 5 minutes is excessive and unnecessary for a routine assessment. Counting for 15 seconds and multiplying by 4 is not as precise as a full-minute count. Pulse and respirations should not be checked simultaneously; instead, the nurse should count respirations unobtrusively while appearing to take the child's pulse. Therefore, the correct approach is to count the child's respirations for 1 full minute to obtain an accurate assessment.

4. Specific gravity in urinalysis:

• A. compares the concentration of urine to that of distilled water
• B. is useless when the patient is dehydrated
• C. can only be measured using a refractometer
• D. None of the above

Correct answer: A

Rationale: Specific gravity in urinalysis measures the concentration of solutes in urine compared to that of distilled water. This comparison helps in assessing the kidney's ability to concentrate urine properly. It is a valuable test even in dehydrated patients as it provides insights into renal function. Specific gravity can be measured using various methods, including a refractometer or reagent strips. Normal specific gravity readings of human urine typically range from 1.005 to 1.030. Choice A is correct as it accurately describes the purpose of specific gravity in urinalysis. Choices B and C are incorrect as specific gravity remains relevant in dehydrated patients and can be measured using different techniques, not solely a refractometer.

5. A patient is bleeding profusely from an injury near her wrist. Which of the following first aid procedures would be MOST appropriate?

• A. Place a tourniquet on her arm above the injury.
• B. Place pressure on her brachial artery.
• C. Place pressure on her radial nerve.
• D. Cover the bleeding area with wet towels.

Correct answer: B

Rationale: The most appropriate first aid procedure for a patient bleeding profusely from an injury near the wrist is to place pressure on her brachial artery. Applying pressure to the brachial pulse point will help slow down the bleeding. Placing a tourniquet on her arm above the injury is not recommended as it could potentially inhibit blood flow, leading to tissue necrosis. Pressing on the radial nerve or covering the bleeding area with wet towels are not effective in controlling bleeding and may not address the underlying cause.
