Nursing Elites

1. A client is admitted for a surgical procedure. Which of the following preexisting conditions can be a contraindication for the use of Ketamine as an intravenous anesthetic?

• A. Peptic ulcer disease
• B. Breast cancer
• C. Diabetes mellitus
• D. Schizophrenia

Correct answer: D

Rationale: Ketamine is known to produce psychological effects, such as hallucinations. Therefore, individuals with schizophrenia are at increased risk of experiencing exacerbation of their symptoms if given Ketamine, making it a contraindication for its use as an intravenous anesthetic. Peptic ulcer disease, breast cancer, and diabetes mellitus are not contraindications for Ketamine use as an intravenous anesthetic.

2. A healthcare provider in an emergency unit is reviewing the medical record of a client who is being evaluated for angle-closure glaucoma. Which of the following findings are indicative of this condition?

• A. Insidious onset of painless loss of vision
• B. Gradual reduction in peripheral vision
• C. Severe pain around the eyes
• D. Intraocular pressure of 12mm Hg

Correct answer: C

Rationale: Severe pain around the eyes that radiates over the face is a characteristic symptom of acute angle-closure glaucoma. This intense pain is typically accompanied by other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. The acute rise in intraocular pressure leads to these symptoms, indicating a medical emergency that requires immediate attention to prevent vision loss. Choices A, B, and D are incorrect. Insidious onset of painless loss of vision is more suggestive of conditions like age-related macular degeneration or diabetic retinopathy. Gradual reduction in peripheral vision is commonly seen in conditions like open-angle glaucoma. An intraocular pressure of 12mm Hg is within the normal range and not indicative of the acute rise seen in angle-closure glaucoma.

3. A healthcare provider is caring for several clients who came to the clinic for a seasonal influenza immunization. The healthcare 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 with no health problems
• B. 17-year-old with a hypersensitivity to Penicillin
• C. 25-year-old who is pregnant
• D. 52-year-old who takes a multivitamin supplement

Correct answer: B

Rationale: A 17-year-old can be immunized for influenza with the LAIV via nasal spray. A hypersensitivity to penicillin is not a contraindication for an influenza immunization. Nasal spray influenza vaccine is generally recommended for healthy individuals between 2 and 49 years old. Choices A, C, and D are not candidates for nasal spray influenza vaccine. A 1-year-old is too young, pregnant individuals should not receive the nasal spray, and age is a factor for the use of the nasal spray vaccine.

4. A client has a new prescription for Warfarin. The nurse should identify that the concurrent use of which of the following medications increases the client's risk of bleeding?

• A. Vitamin K
• B. Calcium carbonate
• C. Acetaminophen
• D. Ranitidine

Correct answer: C

Rationale: The correct answer is Acetaminophen (Choice C). Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking Warfarin. It can potentiate the anticoagulant effect of Warfarin, leading to an increased risk of bleeding. Vitamin K (Choice A) is actually used to reverse the effects of Warfarin in case of over-anticoagulation, so it does not increase the risk of bleeding. Calcium carbonate (Choice B) and Ranitidine (Choice D) do not significantly interact with Warfarin to increase the risk of bleeding.

5. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.
