A nurse is preparing to administer methylprednisolone acetate (Depo-Medrol) 10 mg by IV bolus. The amount available is 40 mg/mL. How many mL should the nurse administer?
Correct Answer: 0.3
Rationale: Correct Answer: 0.3 mL
Rationale:
1. Calculate the total dose needed: 10 mg.
2. Determine the concentration: 40 mg/mL.
3. Use the formula: dose needed / concentration available = volume to administer.
4. Plug in the values: 10 mg / 40 mg/mL = 0.25 mL.
5. Round up to the nearest practical dose increment: 0.3 mL.
Summary:
Choice A (0.5 mL): Incorrect, as it does not accurately calculate the volume needed.
Choices B-G: Irrelevant, as they do not follow the correct calculation method.

A nurse is working with a newly hired nurse who is administering meds to clients. Which of the following actions by the newly hired nurse indicates an understanding of med error prevention?
- A. Taking all meds out of the unit-dose wrappers before entering the client's room.
- B. Checking with the provider when a single dose requires administration of multiple tablets.
- C. Administering a med, then looking up the usual dosage range.
- D. Relying on another nurse to clarify a med prescription.
Correct Answer: B
Rationale: Correct Answer: B
Rationale: Choice B demonstrates understanding of med error prevention because checking with the provider when a single dose requires administration of multiple tablets ensures accuracy in medication administration. This step helps prevent medication errors related to dosage calculation and administration. By consulting the provider, the nurse confirms the correct dosage and avoids potential overdosing or underdosing, which are common causes of medication errors. This action aligns with the principles of safe medication administration and prioritizes patient safety.
Incorrect Choices:
A: Taking all meds out of the unit-dose wrappers before entering the client's room can lead to medication mix-ups and errors, as it increases the risk of confusion and misidentification of medications.
C: Administering a med, then looking up the usual dosage range is risky as it may result in incorrect dosing and jeopardize patient safety.
D: Relying on another nurse to clarify a med prescription is problematic as it bypasses the responsibility of verifying medication orders directly with the prescriber
A nurse is caring for an 82-year-old client in the ER who has an oral body temperature of 38.3°C (101°F), a pulse rate of 114/min, & a respiratory rate of 22/min. He is restless & his skin is warm. Which of the following are appropriate nursing interventions for this client? Select all.
- A. Obtain culture specimens before initiating antimicrobials
- B. Restrict the client's oral fluid intake
- C. Encourage the client to limit activity & rest
- D. Allow the client to shiver to dispel excess heat
- E. Assist the client with oral hygiene frequently
Correct Answer: A, C, E
Rationale: Correct Answer: A, C, E
Rationale:
A: Obtaining culture specimens before initiating antimicrobials is crucial to identify the specific pathogen causing the infection and guide appropriate treatment.
C: Encouraging the client to limit activity & rest helps conserve energy and promote recovery in the presence of infection.
E: Assisting the client with oral hygiene frequently helps prevent further infection and maintain oral health, which is important in the elderly population.
Incorrect Choices:
B: Restricting the client's oral fluid intake is not appropriate as hydration is essential, especially in the presence of fever and infection.
D: Allowing the client to shiver to dispel excess heat is not recommended as it can lead to increased metabolic demand and discomfort for the client.
A nurse is caring for a client who has had diarrhea for the past 4 days. When assessing the client, the nurse should expect which of the following findings? Select all.
- A. Bradycardia
- B. Hypotension
- C. Fever
- D. Poor skin turgor
- E. Peripheral edema
Correct Answer: B, C, D
Rationale: The correct answers are B, C, and D. Diarrhea leads to fluid loss, causing hypotension (B) due to decreased blood volume, fever (C) as a result of dehydration and infection, and poor skin turgor (D) due to decreased tissue hydration. Bradycardia (A) is unlikely as the body compensates for dehydration with increased heart rate. Peripheral edema (E) is not expected as dehydration leads to fluid depletion, not retention.
A nurse is caring for a client who is at high risk for aspiration. Which of the following is an appropriate nursing intervention?
- A. Give the client thin liquids.
- B. Instruct the client to tuck her chin when swallowing.
- C. Have the client use a straw.
- D. Encourage the client to lie down and rest after meals.
Correct Answer: B
Rationale: The correct answer is B: Instruct the client to tuck her chin when swallowing. This intervention helps prevent aspiration by closing off the airway during swallowing, reducing the risk of food or liquids entering the lungs. Tucking the chin also helps direct the food or liquid down the esophagus. Giving thin liquids (choice A) can increase the risk of aspiration. Using a straw (choice C) may also increase the risk by bypassing the natural protective mechanisms. Encouraging the client to lie down after meals (choice D) can lead to aspiration due to decreased muscle tone and gravity assisting in food or liquid entering the airway.
A nursing instructor is reviewing the wound healing process with a group of nursing students. They should be able to identify which of the following alterations as a wound or injury that heals by secondary intention? Select all.
- A. Stage III pressure ulcer
- B. Sutured surgical incision
- C. Casted bone fracture
- D. Laceration sealed with adhesive
- E. Open burn area
Correct Answer: A, E
Rationale: The correct answers are A and E because wounds healing by secondary intention involve tissue loss and heal from the bottom up with granulation tissue filling in the wound. A Stage III pressure ulcer and an open burn area are examples of wounds that heal by secondary intention due to tissue loss.
Choices B and D are incorrect because sutured surgical incisions and lacerations sealed with adhesive heal by primary intention, where wound edges are approximated and heal with minimal scarring. Choice C, a casted bone fracture, is incorrect as fractures heal through a different process involving the formation of callus and subsequent bone remodeling, not by secondary intention healing.
