Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. A client who has a new prescription for warfarin (Coumadin) is receiving discharge instructions. Which statement indicates the client understands the teaching?

• A. I will take my warfarin at the same time every day.
• B. I should increase my intake of green leafy vegetables.
• C. I should use a soft-bristled toothbrush while taking this medication.
• D. I should avoid drinking alcohol while taking this medication.

Correct answer: C

Rationale: The correct answer is C: 'I should use a soft-bristled toothbrush while taking this medication.' Using a soft-bristled toothbrush is crucial as it helps prevent bleeding gums, which is a potential side effect of warfarin therapy. Option A about taking warfarin at the same time every day is a good practice but does not directly relate to preventing side effects. Option B suggesting an increase in green leafy vegetables can interfere with warfarin's anticoagulant effects due to their vitamin K content. Option D advising to avoid alcohol is generally recommended but is not directly related to the specific side effects of warfarin.

3. During a blood transfusion, which observation indicates that the client is experiencing a transfusion reaction?

• A. The client reports feeling warm and flushed.
• B. The client develops a rash on the chest and back.
• C. The client experiences chills and a fever.
• D. The client complains of back pain and shortness of breath.

Correct answer: D

Rationale: Complaints of back pain and shortness of breath are classic signs of a transfusion reaction, specifically indicating a hemolytic reaction. This reaction can lead to the release of hemoglobin into the bloodstream, causing back pain and shortness of breath due to clot formation in the blood vessels, leading to decreased oxygen delivery. Warmth, flushing, rash, chills, and fever are more commonly associated with allergic reactions or febrile non-hemolytic reactions during transfusions. Therefore, options A, B, and C are incorrect in this context.

4. A hospitalized male client is receiving nasogastric tube feedings via a small-bore tube and a continuous pump infusion. He reports that he had a bad bout of severe coughing a few minutes ago but feels fine now. What action is best for the LPN/LVN to take?

• A. Record the coughing incident. No further action is required at this time.
• B. Stop the feeding, explain to the family why it is being stopped, and notify the healthcare provider.
• C. After clearing the tube with 30 ml of air, check the pH of fluid withdrawn from the tube.
• D. Inject 30 ml of air into the tube while auscultating the epigastrium for gurgling.

Correct answer: C

Rationale: After a client experiences severe coughing following nasogastric tube feedings, it is crucial to verify proper tube placement. Checking the pH of fluid withdrawn from the tube helps confirm the tube's correct positioning. Option A is incorrect because further action is necessary to ensure the client's safety. Option B is inappropriate as it suggests stopping the feeding without assessing the tube's placement. Option D is incorrect as injecting air into the tube may lead to further complications if the tube is not positioned correctly.

5. During a home safety assessment for a client receiving supplemental oxygen, which observation should the nurse identify as proper safety protocol?

• A. The client uses non-acetone nail polish remover.
• B. The client uses an electric razor for shaving.
• C. The client cleans their oxygen equipment weekly.
• D. The client uses wool blankets.

Correct answer: A

Rationale: The correct answer is A. Using non-acetone nail polish remover is crucial for clients on supplemental oxygen as acetone is flammable and poses a safety risk. Acetone can react with oxygen, increasing the fire hazard. Choices B, C, and D are incorrect. Electric razors can generate sparks, which are dangerous near oxygen due to the risk of ignition. While cleaning oxygen equipment is important, the type of nail polish remover used is more critical for immediate safety. Wool blankets can create static electricity, increasing the risk of fire around oxygen due to its flammability.
