Adult Health 2 Final Exam
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. What should the nurse prioritize when providing discharge instructions to a client with a new colostomy?
- A. Skin care around the stoma site
- B. The schedule for colostomy bag replacement
- C. Techniques for odor control
- D. Dietary modifications
Correct answer: A
Rationale: Correct answer: Skin care around the stoma site. Proper skin care around the stoma site is crucial for preventing skin irritation and infection, which are common issues for patients with new colostomies. While the schedule for colostomy bag replacement (Option B) is important, it is not the priority during initial discharge instructions. Techniques for odor control (Option C) are relevant but secondary to skin care for a new colostomy. Dietary modifications (Option D) may be discussed later but are not the priority at this stage.
3. The healthcare provider is assessing a client with a suspected diagnosis of appendicitis. Which symptom is most indicative of this condition?
- A. Right upper quadrant pain
- B. Nausea and vomiting
- C. Rebound tenderness at McBurney's point
- D. Hematuria
Correct answer: C
Rationale: Rebound tenderness at McBurney's point is a classic sign of appendicitis. This symptom is due to irritation of the peritoneum when pressure is released during palpation. Right upper quadrant pain (Choice A) is more commonly associated with gallbladder issues. Nausea and vomiting (Choice B) can occur in various abdominal conditions and are not specific to appendicitis. Hematuria (Choice D) is the presence of blood in the urine and is not a typical symptom of appendicitis.
4. 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.
5. During a bed bath, the nurse observes that a client's IV site is red and swollen. What should the nurse do first?
- A. Discontinue the IV under physician's guidance
- B. Apply a warm compress to the site
- C. Notify the physician
- D. Document the appearance of the site and continue the bath
Correct answer: C
Rationale: The correct first action when a nurse observes a red and swollen IV site during a bed bath is to notify the physician. This is crucial because prompt reporting allows for immediate intervention to prevent further complications. Discontinuing the IV (Choice A) should only be done under the physician's guidance to avoid any adverse effects and ensure proper care. Applying a warm compress (Choice B) may not address the underlying issue and could potentially worsen the situation if the cause is an infection or infiltration. Documenting the site's appearance and continuing the bath (Choice D) without immediate action might delay necessary treatment, leading to potential complications.
