NCLEX RN Predictor Exam

1. A healthcare professional is asked to draw blood in the antecubital (AC) space. Which of the following veins are found in the AC?

A. Cephalic
B. Median cubital
C. Basilic
D. All of the above

Correct answer: D

Rationale: The correct answer is 'All of the above.' All three of these veins - the cephalic, median cubital, and basilic veins - are located in the antecubital space, which is the area in front of the elbow on the arm. The cephalic vein runs along the outer side of the arm, the basilic vein runs along the inner side of the arm, and the median cubital vein is a connecting vein between the cephalic and basilic veins. Therefore, all three veins can be accessed when drawing blood from the antecubital space. Choices A, B, and C are incorrect because each of these veins individually can be found in the antecubital space.

2. During the general survey, what action is a component of the assessment?

A. Observing the patient's body stature and nutritional status
B. Interpreting the subjective information reported by the patient
C. Measuring the patient's temperature, pulse, respirations, and blood pressure
D. Observing specific body systems during the physical assessment

Correct answer: A

Rationale: During the general survey, the nurse assesses the patient's overall appearance, body structure, mobility, and behavior, which includes observing body stature and nutritional status. Interpreting subjective information reported by the patient is part of the subjective data collection process and not the general survey. Measuring vital signs like temperature, pulse, respirations, and blood pressure is part of a focused physical examination, not the general survey. Additionally, observing specific body systems while performing a physical assessment is more specific and focused than the general survey.

3. When measuring the vital signs of a 6-month-old infant, which action by the nurse is correct?

A. Respirations are measured first, followed by pulse and temperature.
B. Vital signs should be measured as frequently as in an adult.
C. Procedures are explained to the parent, and the infant is encouraged to handle the equipment.
D. The nurse should first measure the infant's vital signs before performing a physical examination.

Correct answer: A

Rationale: When assessing vital signs in a 6-month-old infant, the correct order is to measure respirations first, followed by pulse and temperature. This sequence is important to avoid potential alterations in respiratory and pulse rates caused by factors like crying or discomfort. Measuring the temperature first, especially rectally, may lead to an increase in respiratory and pulse rates, which can skew the results. It is crucial to follow this specific order to obtain accurate baseline values. Therefore, option A is the correct choice. Option B is incorrect as the frequency of measuring vital signs in infants differs based on individual needs rather than being consistently more frequent than in adults. Option C is not directly related to the correct sequence for measuring vital signs in infants. Option D is incorrect because the physical examination typically follows the assessment of vital signs in clinical practice.

4. Which contraindication should be assessed for prior to administering an immunization to a child?

A. Mild cold symptoms
B. Chronic asthma
C. Depressed immune system
D. Allergy to eggs

Correct answer: C

Rationale: Before administering immunizations to children, it is crucial to assess for contraindications. A depressed immune system, such as that seen in conditions like HIV or due to chemotherapy, is a significant contraindication. Immunizations may not be safe or effective in children with compromised immune systems. Mild cold symptoms, although not ideal, are not a contraindication for routine immunizations. Chronic asthma, while a consideration, is not a direct contraindication for routine immunizations. Allergy to eggs is a contraindication for specific vaccines, such as influenza vaccine that is grown in eggs, but it is not a contraindication for all immunizations.

5. Why should direct care providers avoid glued-on artificial nails?

A. Interfere with dexterity of the fingers.
B. Could fall off in a patient's bed.
C. Harbor microorganisms.
D. Can scratch a patient.

Correct answer: C

Rationale: Direct care providers, including nurses, should avoid glued-on artificial nails because studies have shown that artificial nails, especially when cracked, broken, or split, create crevices where microorganisms can thrive and multiply. This can lead to an increased risk of transmitting infections to patients. Therefore, the primary reason for avoiding glued-on artificial nails is their potential to harbor harmful microorganisms, making option C the correct choice. Options A, B, and D are incorrect because while they may present some issues, the primary concern is the risk of microbial contamination associated with artificial nails.
