Nursing Elites

1. When admitting a client diagnosed with active tuberculosis to isolation, which infection control measures should the nurse implement?

• A. Negative pressure environment
• B. Contact precautions
• C. Droplet precautions
• D. Protective environment

Correct answer: A

Rationale: The correct answer is A: Negative pressure environment. Tuberculosis is transmitted through airborne particles, so a negative pressure room is essential to prevent the spread of the bacteria. Choice B, contact precautions, are used for infections spread by direct or indirect contact, not for tuberculosis. Choice C, droplet precautions, are for infections transmitted through respiratory droplets, not airborne particles like tuberculosis. Choice D, protective environment, is used for protecting immunocompromised patients from outside pathogens, not for preventing the spread of tuberculosis.

2. After successful resuscitation, a client is given propranolol and transferred to the Intensive Coronary Care Unit (ICCU). On admission, magnesium sulfate 4 grams IV in 250 ml D5W at one gram/hour. Which assessment findings require immediate intervention by the nurse?

• A. Dark amber urine draining via an indwelling catheter at a rate of 40 ml per hour
• B. Serum calcium of 9.0 mg/dl (2.2 mmol/L SI) and magnesium of 1.8 mg/dl or Eq/L (0.74 mmol/L SI)
• C. Sinus rhythm at 72 beats/minute and peripheral blood pressure of 99/62
• D. Respiratory rate of 10 breaths per minute

Correct answer: D

Rationale: The correct answer is D. A low respiratory rate of 10 breaths per minute is indicative of possible magnesium toxicity, which can be a serious condition requiring immediate intervention. It is a critical finding that needs prompt attention to prevent further complications. The other options are not as urgent: A - dark amber urine may indicate dehydration but does not require immediate intervention, B - serum calcium and magnesium levels are within normal limits, C - sinus rhythm and blood pressure values are also within normal range and do not require immediate action.

3. The nurse is caring for a laboring 22-year-old primigravida following administration of regional anesthesia. In planning care for this client, what nursing intervention has the highest priority?

• A. Raising the side rails and placing the call bell within reach
• B. Teaching the client how to push to decrease the length of the second stage of labor
• C. Timing and recording uterine contractions
• D. Positioning the client for proper distribution of anesthesia

Correct answer: D

Rationale: The highest priority nursing intervention for a laboring client following administration of regional anesthesia is to position the client for proper distribution of anesthesia. Proper positioning ensures effective pain management during labor, optimizing the effects of the regional anesthesia. While raising the side rails and placing the call bell within reach (choice A) is important for safety, teaching the client how to push (choice B) and timing and recording uterine contractions (choice C) are vital aspects of care but are not the highest priority immediately after administering regional anesthesia.

4. The healthcare provider prescribes potassium chloride 25 mEq in 500 ml D5W to infuse over 6 hours. The available 20 ml vial of potassium chloride is labeled '10 mEq/5 ml.' How many ml of potassium chloride should the nurse add to the IV fluid?

• A. 12.5
• B. 5
• C. 10
• D. 20

Correct answer: B

Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.

5. Which techniques should be used to administer an intradermal (ID) injection for a Mantoux test to screen for tuberculosis (TB)? Select all that apply.

• A. Observe for an intradermal bleed after the antigen is injected
• B. Select an ID site using the volar surface of the forearm
• C. Use a 26 or 27-gauge needle with a length of 1/4 to 5/8 inches on a 1 ml calibrated syringe
• D. Ensure that the needle is inserted into the skin with the bevel up

Correct answer: A

Rationale: Observing for an intradermal bleed after the antigen is injected is a proper technique for an ID injection. This is important to confirm the correct placement of the injection. Choice B is correct because the recommended site for an ID injection for a Mantoux test is the volar surface of the forearm. Choice C is incorrect because the standard needle size for an ID injection is usually 26 or 27 gauge with a length of 1/4 to 5/8 inches, not 25 gauge with a length of 1/2 inch. Choice D is incorrect because the needle should be inserted into the skin with the bevel facing up, not down.
