A client who weighs 187 lb has an order to receive enoxaparin (Lovenox) 1 mg/kg. This drug is available in a concentration of 30 mg/0.3 mL. What dose would the nurse administer in milliliters?
- A. 0.85 mL
- B. 0.9 mL
- C. 0.95 mL
- D. 1.0 mL
Correct Answer: A
Rationale: Calculation: 187 lb ÷ 2.2 = 85 kg. Dose = 85 kg × 1 mg/kg = 85 mg. Concentration = 30 mg/0.3 mL = 100 mg/mL. Volume = 85 mg ÷ 100 mg/mL = 0.85 mL. Thus, the nurse administers 0.85 mL.

The nurse is providing discharge teaching for a client post-inguinal herniorrhaphy. Which statement by the client indicates a need for further teaching?
- A. I'll avoid heavy lifting for about 6 weeks.
- B. I can take a shower tomorrow.
- C. I'll call the doctor if I have a fever.
- D. I can resume sexual activity next week.
Correct Answer: D
Rationale: Resuming sexual activity within a week post-inguinal herniorrhaphy may strain the surgical site, indicating a need for further teaching to delay such activities for 4–6 weeks. The other statements align with appropriate postoperative care. CN: Health promotion and maintenance; CL: Evaluate
When suctioning a tracheostomy or laryngectomy tube, the nurse should follow which of the following procedures?
- A. Use a sterile catheter each time the client is suctioned.
- B. Clean the catheter in sterile water after each use and reuse for no longer than 8 hours.
- C. Protect the catheter in sterile packaging between suctioning episodes.
- D. Use a clean catheter with each suctioning, and disinfect it in hydrogen peroxide between uses.
Correct Answer: A
Rationale: Using a sterile catheter each time minimizes infection risk in the airway. Reusing catheters, even if cleaned, increases infection risk.
The nurse learns that a client who is scheduled for a tonsillectomy has been taking 40 mg of oral prednisone daily for the last week for poison ivy on his leg. What is the nurse's best action?
- A. Document the prednisone with current medications.
- B. Notify the surgeon of the poison ivy.
- C. Notify the anesthesiologist of the prednisone administration.
- D. Send the client to surgery.
Correct Answer: C
Rationale: Prednisone use affects adrenal function and stress response, increasing risks during anesthesia. Notifying the anesthesiologist ensures proper perioperative management, such as stress-dose steroids.
A client uses timolol maleate (Timoptic) eyedrops. The expected outcome of this beta-adrenergic blocker is to control glaucoma by:
- A. Constricting the pupils.
- B. Dilating the canals of Schlemm.
- C. Reducing aqueous humor formation.
- D. Improving the ability of the ciliary muscle to contract.
Correct Answer: C
Rationale: Timolol maleate, a beta-adrenergic blocker, reduces intraocular pressure by decreasing the production of aqueous humor in the eye.
A client with acute chest pain is receiving I.V. morphine sulfate. Which of the following results are intended effects of morphine in this client? Select all that apply.
- A. Reduces myocardial oxygen consumption.
- B. Promotes reduction in respiratory rate.
- C. Prevents ventricular remodeling.
- D. Reduces blood pressure and heart rate.
- E. Reduces anxiety and fear.
Correct Answer: A,D,E
Rationale: Morphine reduces pain, which lowers myocardial oxygen demand (A), decreases blood pressure and heart rate through vasodilation and reduced sympathetic response (D), and alleviates anxiety and fear (E). It does not prevent ventricular remodeling or directly reduce respiratory rate in this context.
