Nursing Elites

1. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

2. The nurse is assessing a client with a suspected pulmonary embolism (PE). Which symptom is most indicative of this condition?

• A. Bilateral leg swelling.
• B. Sudden onset of chest pain.
• C. Gradual onset of dyspnea.
• D. Decreased breath sounds on auscultation.

Correct answer: C

Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.

3. The nurse is caring for a client postoperatively following a thyroidectomy. Which assessment finding should be reported to the healthcare provider immediately?

• A. Hoarseness of the voice.
• B. Slight swelling at the incision site.
• C. Tingling around the mouth.
• D. Mild fever.

Correct answer: C

Rationale: Tingling around the mouth should be reported to the healthcare provider immediately as it may indicate hypocalcemia, a potential complication after thyroidectomy. Hoarseness of the voice is common postoperatively due to surgical manipulation, slight swelling at the incision site is a normal response, and a mild fever can be expected after surgery. However, tingling around the mouth suggests a potential calcium imbalance, which requires prompt attention to prevent serious complications.

4. A client with a leg fracture reports increased pain and swelling. What should the nurse suspect?

• A. Compartment syndrome
• B. Deep vein thrombosis
• C. Wound infection
• D. All of the above

Correct answer: A

Rationale: Increased pain and swelling in a fracture could indicate compartment syndrome, a serious condition requiring urgent care. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to compromised blood flow and potential tissue damage. Deep vein thrombosis is less likely in this scenario as the symptoms are more indicative of compartment syndrome. Wound infection would typically present with localized signs of infection at the wound site, such as redness, warmth, and purulent drainage, rather than diffuse pain and swelling.

5. The nurse is teaching a client about the administration of a subcutaneous injection. Which site is most appropriate for this type of injection?

• A. Deltoid muscle
• B. Dorsogluteal muscle
• C. Ventrogluteal muscle
• D. Abdomen

Correct answer: D

Rationale: The abdomen is a common site for subcutaneous injections due to its accessibility and ample subcutaneous tissue. Subcutaneous injections are typically given in areas with a layer of fat between the skin and muscle, such as the abdomen, to allow for slow and consistent absorption of the medication. The deltoid muscle is more appropriate for intramuscular injections, not subcutaneous. The dorsogluteal muscle and ventrogluteal muscle are also more suited for intramuscular injections, not subcutaneous.
