Nursing Elites

1. What is the primary role of the sinoatrial (SA) node in the heart?

• A. Pacemaker of the heart
• B. Blood pressure regulation
• C. Electrical conduction delay
• D. Stimulating muscle contraction

Correct answer: A

Rationale: The correct answer is A: Pacemaker of the heart. The SA node, known as the natural pacemaker, initiates the electrical impulses that set the rhythm for the heartbeat. It is responsible for coordinating the heart's contractions by generating electrical signals at regular intervals. Choice B is incorrect as the SA node's primary function is not related to blood pressure regulation. Choice C is incorrect as the SA node does not cause electrical conduction delay but rather initiates and conducts the electrical impulses. Choice D is incorrect as the SA node does not directly stimulate muscle contraction but rather initiates the electrical events that lead to muscle contraction.

2. What is the most appropriate nursing action when a patient on anticoagulant therapy develops sudden, severe back pain?

• A. Administer pain medication
• B. Apply a cold compress to the back
• C. Assess for signs of internal bleeding
• D. Reposition the patient for comfort

Correct answer: C

Rationale: When a patient on anticoagulant therapy experiences sudden, severe back pain, the priority nursing action is to assess for signs of internal bleeding. Severe back pain in this context could be indicative of internal bleeding, such as a retroperitoneal bleed, which is a critical condition requiring immediate attention. Administering pain medication or applying a cold compress may mask or delay the identification of a potentially life-threatening situation. Repositioning the patient for comfort is not the priority when internal bleeding needs to be ruled out.

3. A nurse is assessing a day-old infant for jaundice. Which of the following is the best method for this?

• A. Applying pressure over a bony area such as the forehead and evaluating the skin color after the pressure is removed
• B. Assessing the color of the infant’s hands and feet
• C. Assessing the infant’s tongue
• D. Assessing the infant’s arms and legs

Correct answer: A

Rationale: The correct answer is A. Applying pressure over a bony area and evaluating the skin color after the pressure is removed is the most accurate method for assessing jaundice in a day-old infant. This technique helps in identifying any yellowing of the skin, which is a key indicator of jaundice. Choices B, C, and D are less effective methods for assessing jaundice in a newborn. Assessing the color of the hands and feet may not give a reliable indication of jaundice, while evaluating the tongue, arms, and legs are not as specific or accurate as applying pressure over a bony area.

4. While caring for a client with an AV fistula in the left forearm, the nurse observed a palpable buzzing sensation over the fistula. What action should the nurse take?

• A. Loosen the dressing of the fistula
• B. Report the presence of a bounding pulse
• C. Document that the fistula is intact
• D. Apply gentle pressure over the site

Correct answer: C

Rationale: The correct answer is C: Document that the fistula is intact. The palpable buzzing sensation (known as a thrill) over the AV fistula indicates proper functioning. It is essential for the nurse to document this finding to ensure ongoing monitoring of the fistula's status. Choices A, B, and D are incorrect. Choice A is incorrect because there is no indication to loosen the dressing. Choice B is incorrect as a bounding pulse is not associated with the palpable buzzing sensation of a thrill. Choice D is incorrect as applying pressure over the site is not necessary for this situation.

5. During a routine prenatal visit at the antepartal clinic, a multipara at 35-weeks gestation presents with 2+ edema of the ankles and feet. Which additional information should the PN report to the RN?

• A. Due date
• B. Blood pressure
• C. Gravida and parity
• D. Fundal height

Correct answer: B

Rationale: Blood pressure is the most critical information to report to the RN in this scenario. The presence of edema, along with high blood pressure, can be indicative of preeclampsia, a severe condition in pregnancy. Monitoring blood pressure is essential for assessing the patient's condition and taking appropriate actions if necessary. Choices A, C, and D are not as urgent in this situation. The due date, gravida, and parity are important for overall assessment but do not address the immediate concern of potential preeclampsia. Fundal height is used to assess fetal growth and position but is not the priority when edema and high blood pressure are present.
