1. Which of the following lab values is elevated first after a client has a myocardial infarction?

• A. LDH
• B. troponin
• C. CPK
• D. SGOT

Correct answer: B

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

2. Why is padding on a restraint helpful?

• A. To distribute pressure so that bony prominences do not receive pressure when a client pulls against the restraints.
• B. To help the client feel more secure.
• C. To keep infection and wounds at bay.
• D. To keep restraints in place.

Correct answer: A

Rationale: Padding on a restraint helps distribute pressure to prevent bony prominences from bearing excessive pressure when a client pulls against the restraints. This is crucial to avoid tissue damage caused by ischemia. The correct answer focuses on the physiological benefit of padding in reducing pressure on vulnerable areas to prevent harm. Choice B is incorrect as the primary purpose of padding is not emotional comfort but preventing physical harm. Choice C is incorrect as while padding can indirectly help prevent infection and wounds by reducing pressure, its primary function is pressure distribution. Choice D is incorrect as the main purpose of padding is not to keep the restraints in place but to protect the client's skin and tissues from pressure-related injuries.

3. A nurse is preparing to administer medications to a client via a nasogastric (NG) tube. Before administering the medication, the nurse must first take which action?

• A. Check the client's apical pulse
• B. Check when the last feeding was given
• C. Check the placement of the tube
• D. Check when the last medications were given

Correct answer: C

Rationale: Before administering medications through an NG tube, the nurse must first check the placement of the tube to prevent aspiration. This is done by aspirating gastric contents and measuring the pH. Checking the client's apical pulse is unrelated to NG tube medication administration. Checking when the last feeding was given is important but not a priority before administering medications. Checking when the last medications were given is also not directly related to ensuring the safe administration of medications through an NG tube. Ensuring the correct placement of the tube is crucial to prevent complications such as pulmonary aspiration.

4. The mother of a child who weighs 45 lb asks a nurse about car safety seats. The nurse tells the mother to place the child in which car safety seat?

• A. Car safety seat in the back seat in a face-forward position
• B. Booster seat with one of the car's seat belts placed over the child
• C. Booster seat in a rear-facing position in the front seat
• D. Car safety seat in a face-forward position in the front seat

Correct answer: B

Rationale: The correct answer is to place the child in a booster seat with one of the car's seat belts placed over the child. A child needs to remain in a car safety seat until he or she weighs 40 lb. Once the child has outgrown the car safety seat, a booster seat is used. Booster seats are designed to raise the child high enough so that the restraining straps are correctly positioned over the child's chest and pelvis, providing optimal safety. Placing a child in a booster seat in a rear-facing position in the front seat is incorrect as children should not be seated in the front seat due to potential airbag-related injuries. Additionally, car safety seats are used for children weighing less than 40 lb and are placed in the middle of the back seat in a rear-facing position for maximum protection.

5. When removing a client's gown with an intravenous line, what should the nurse do?

• A. temporarily disconnect the intravenous tubing at a point close to the client and thread it through the gown
• B. cut the gown with scissors
• C. thread the bag and tubing through the gown sleeve, keeping the line intact
• D. temporarily disconnect the tubing from the intravenous container and thread it through the gown

Correct answer: C

Rationale: The correct action when removing a client's gown with an intravenous line is to thread the bag and tubing through the gown sleeve while keeping the line intact. This method ensures that the system remains sterile and reduces the risk of infection. Temporarily disconnecting the tubing at a point close to the client or from the container introduces the potential for contamination. Cutting the gown with scissors should only be done in emergencies as it is not a standard practice and can compromise the integrity of the intravenous line. Therefore, the most appropriate and safe method is to thread the bag and tubing through the gown sleeve.
