NCLEX RN Predictor Exam

1. What is the BEST blood collection location for a newborn?

A. the AC
B. the veins of the forehead
C. the heel
D. the fingertips

Correct answer: C

Rationale: When collecting blood from newborns, it is safest and most commonly done by collecting blood from the lateral or medial aspect of the baby's heel. This location is preferred due to the accessibility of the veins and the minimal discomfort caused to the newborn. Veins in the forehead are not commonly used for blood collection in newborns. The fingertips are not optimal for blood collection in newborns due to their small size and the potential for causing discomfort. The AC (antecubital) area, typically used in adults for blood collection, is not recommended for newborns due to the size of their veins and the potential risk of injury.

2. In which situation would the nurse use bimanual palpation technique?

A. Palpating the thorax of an infant
B. Palpating the kidneys and uterus
C. Assessing pulsations and vibrations
D. Assessing the presence of tenderness and pain

Correct answer: B

Rationale: Bimanual palpation involves using both hands to envelop or capture specific body parts or organs like the kidneys, uterus, or adnexa. This technique is particularly useful for assessing the size, shape, consistency, and mobility of deep organs like the kidneys and uterus. Palpating the thorax of an infant (Choice A) is usually done with a different technique like gentle, single-handed palpation. Assessing pulsations and vibrations (Choice C) and assessing tenderness and pain (Choice D) typically do not require the use of bimanual palpation, making Choices A, C, and D incorrect.

3. What is the primary route of transmission of MRSA?

A. Shared needles
B. Hands of healthcare workers
C. Items in the healthcare environment
D. Blood transfusions

Correct answer: B

Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.

4. While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?

A. They are able to make simple associations of ideas
B. They are able to think logically in organizing facts
C. Interpretation of events originates from their own perspective
D. Conclusions are based on previous experiences

Correct answer: B

Rationale: At the age of 10, children are in the concrete operations stage according to Piaget. They are capable of mature thought when allowed to manipulate and organize objects. This means they can think logically, organize facts, and understand cause-and-effect relationships. Choices A, C, and D are incorrect. While simple associations of ideas may occur, the key cognitive ability at this stage is the capacity for logical thought and organization of information. Interpretation of events from their own perspective is more characteristic of younger children, and conclusions based on previous experiences are more aligned with older children or adults.

5. The nurse receives change-of-shift report on the following four patients. Which patient should the nurse assess first?

A. A 23-year-old patient with cystic fibrosis who has pulmonary function testing scheduled
B. A 46-year-old patient on bed rest who is complaining of sudden onset of shortness of breath
C. A 77-year-old patient with tuberculosis (TB) who has four antitubercular medications due in 15 minutes
D. A 35-year-old patient who was admitted the previous day with pneumonia and has a temperature of 100.2 F (37.8 C)

Correct answer: B

Rationale: The correct answer is the 46-year-old patient on bed rest who is complaining of sudden onset of shortness of breath. Patients on bed rest who are immobile are at high risk for deep vein thrombosis (DVT). Sudden onset of shortness of breath in a patient with a DVT suggests a pulmonary embolism, which requires immediate assessment and action such as oxygen administration to maintain adequate oxygenation. The other patients should also be assessed as soon as possible, but they do not present with an immediate life-threatening condition that requires urgent intervention like the patient experiencing sudden shortness of breath.
