Nursing Elites

1. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.8 mL
• B. 0.75 mL
• C. 0.5 mL
• D. 1 mL

Correct answer: A

Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.

2. A healthcare professional is reviewing the medication list of a client who has a new prescription for Metformin to treat type 2 diabetes. Which of the following medications should the healthcare professional identify as placing the client at risk for lactic acidosis?

• A. Metformin
• B. Metoprolol
• C. Lisinopril
• D. Insulin

Correct answer: A

Rationale: Metformin is known to have a risk of causing lactic acidosis, particularly in clients with renal impairment or predisposing conditions. Lactic acidosis is a rare but serious adverse effect of metformin use that can be life-threatening. Metoprolol, Lisinopril, and Insulin do not have a known association with lactic acidosis. Healthcare professionals should monitor clients prescribed metformin carefully, especially those with risk factors, to detect and manage lactic acidosis promptly.

3. Which of the following is the antidote for benzodiazepine toxicity?

• A. Flumazenil
• B. Methylene blue
• C. Deferoxamine
• D. Alkalinize urine

Correct answer: A

Rationale: Flumazenil is the specific antidote for benzodiazepine toxicity. It acts as a competitive antagonist at the benzodiazepine binding site on the GABA receptor, reversing the sedative effects of benzodiazepines. Administration of flumazenil is indicated in cases of benzodiazepine overdose or toxicity to rapidly reverse the central nervous system depression caused by these drugs. It is important to note that flumazenil should be used cautiously in patients with a history of seizures or those who are physically dependent on benzodiazepines, as it can precipitate withdrawal symptoms or seizures.

4. A client with Peptic Ulcer Disease who is taking Sucralfate PO has a new prescription for phenytoin to control seizures. Which of the following instructions should the nurse include?

• A. Take an antacid with the sucralfate.
• B. Take sucralfate with a glass of milk.
• C. Allow a 2-hour interval between these medications.
• D. Chew the sucralfate thoroughly before swallowing.

Correct answer: C

Rationale: Sucralfate can interfere with the absorption of phenytoin. To prevent this interaction, the client should allow a 2-hour interval between taking sucralfate and phenytoin. This interval helps ensure that each medication is absorbed effectively without affecting the other's absorption. Choices A, B, and D are incorrect because taking an antacid with sucralfate, taking sucralfate with a glass of milk, or chewing sucralfate thoroughly before swallowing are not necessary or recommended instructions to prevent the interaction between sucralfate and phenytoin.

5. A nurse is teaching a client who has a new prescription for Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?

• A. Tachycardia
• B. Hypoglycemia
• C. Bradycardia
• D. Hypertension

Correct answer: C

Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect. The client should monitor their pulse regularly and report any significant decreases.
