Nursing Elites

1. What is the antidote for Warfarin?

• A. Vitamin D
• B. Vitamin C
• C. Vitamin K
• D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.

2. A healthcare provider is caring for several clients who came to the clinic for a seasonal influenza immunization. The provider should identify that which of the following clients is a candidate to receive the vaccine via nasal spray rather than an injection?

• A. 1-year-old who has no health problems
• B. 17-year-old who has a hypersensitivity to Penicillin
• C. 25-year-old who is pregnant
• D. 52-year-old who takes a multivitamin supplement

Correct answer: B

Rationale: The correct answer is B. A 17-year-old can receive the influenza vaccine via nasal spray even if they have a hypersensitivity to penicillin, as this is not a contraindication for the influenza immunization. The nasal spray vaccine (LAIV) is a live attenuated vaccine that is suitable for healthy individuals aged 2-49 years. Pregnancy (choice C) is a contraindication for the nasal spray influenza vaccine. Children under 2 years of age (choice A) are also not candidates for the nasal spray. Taking a multivitamin supplement (choice D) is not a determining factor for the type of influenza vaccine a person should receive.

3. A client is receiving Gentamicin. Which of the following laboratory values should the nurse monitor to assess for nephrotoxicity?

• A. Serum sodium.
• B. Serum creatinine.
• C. Serum potassium.
• D. Serum glucose.

Correct answer: B

Rationale: When a client is receiving Gentamicin, the nurse should monitor serum creatinine levels to assess for nephrotoxicity. Gentamicin is known to potentially cause nephrotoxicity, leading to impaired kidney function. Monitoring serum creatinine levels helps in early detection of any kidney damage or dysfunction. Serum sodium, serum potassium, and serum glucose levels are not directly related to nephrotoxicity caused by Gentamicin, so they are not the appropriate values to monitor in this case.

4. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

5. When starting therapy with trastuzumab, which finding should the nurse instruct the client to report?

• A. Dyspnea
• B. Constipation
• C. Tinnitus
• D. Dry mouth

Correct answer: A

Rationale: The correct answer is A: Dyspnea. Dyspnea can indicate pulmonary toxicity, a severe adverse effect of trastuzumab. It is crucial for the client to report any breathing difficulties promptly to ensure timely intervention and prevent further complications. Choices B, C, and D are incorrect because constipation, tinnitus, and dry mouth are not commonly associated with trastuzumab therapy and are not indicative of serious adverse effects that require immediate attention.
