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. To accommodate a patient who is an Orthodox Jew, you would assure that her diet does not include which of the following?

• A. Any combination of meat and milk at the same meal
• B. Fish with scales
• C. Salmon
• D. Grape juice

Correct answer: A

Rationale: The correct answer is A. Orthodox Jewish dietary laws prohibit mixing meat and dairy in the same meal, so to accommodate an Orthodox Jew, you should ensure that their diet does not include any combination of meat and milk at the same meal. Choices B, C, and D are not prohibited in a kosher diet. Fish with scales, including salmon, are typically kosher, and grape juice is also permissible under kosher guidelines if certified. Therefore, options B, C, and D are acceptable in an Orthodox Jewish diet, while option A contradicts their dietary laws.

3. The nurse is preparing to provide wound care for a client. Which step should be done first?

• A. Don procedural gloves
• B. Remove the dressing
• C. Apply prescribed medications to the wound
• D. Don a pair of sterile gloves

Correct answer: A

Rationale: The correct answer is to don procedural gloves first. Donning procedural gloves is essential to protect the nurse from contaminants while removing the old dressing. This step helps maintain aseptic technique and prevents the transfer of microorganisms. Removing the dressing (choice B) should follow after wearing gloves to prevent the spread of pathogens. Applying prescribed medications (choice C) should be done after the wound is cleaned and dressed. Donning a pair of sterile gloves (choice D) is not necessary for initial wound care; procedural gloves are sufficient for standard wound care.

4. Which action should the PN implement when using standard precautions to provide client care?

• A. Apply sterile gloves to obtain a finger stick blood sample
• B. Wear clean exam gloves to perform perineal catheter care
• C. Replace the needle cap after giving an intramuscular injection
• D. Wear a paper gown to prevent transmission of droplet pathogens

Correct answer: B

Rationale: The correct answer is B. When using standard precautions, healthcare providers should wear clean exam gloves to perform perineal catheter care. This approach helps prevent the transmission of pathogens and ensures the safety of both the client and the healthcare provider. Choice A is incorrect because applying sterile gloves for a finger stick blood sample is unnecessary when non-sterile gloves would suffice. Choice C is incorrect because replacing the needle cap after giving an intramuscular injection is not directly related to standard precautions. Choice D is incorrect because wearing a paper gown is not a standard precaution for preventing the transmission of droplet pathogens.

5. During the immediate postoperative period following a total hip replacement, which intervention is most important for the nurse to implement?

• A. Encourage the client to use a walker or cane when ambulating
• B. Keep the client's hip aligned with knees abducted
• C. Teach the client to sit on the side of the bed before standing
• D. Monitor urinary flow via an indwelling catheter

Correct answer: B

Rationale: Keeping the client's hip aligned with the knees abducted is crucial to prevent dislocation of the prosthesis, which is a priority immediately after total hip replacement surgery. This position helps maintain the stability of the new hip joint. Encouraging the client to use a walker or cane (Choice A) is important but not as critical as ensuring proper hip alignment. Teaching the client to sit on the side of the bed before standing (Choice C) is a good practice but not as essential as maintaining hip alignment. Monitoring urinary flow via an indwelling catheter (Choice D) is not directly related to preventing complications immediately after a total hip replacement.
