Adult Health 1 Exam 1
1. Before administration of a stat dose of potassium chloride IV for a client with hypokalemia, what is the most important action for the nurse?
- A. Ensure the IV is flowing freely
- B. Mix the medication thoroughly
- C. Check the client’s electrolyte levels
- D. Obtain a baseline ECG
Correct answer: A
Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.
2. A new father asks the nurse the reason for placing an ophthalmic ointment in his newborn's eyes. What information should the nurse provide?
- A. Possible exposure to an environmental staphylococcus infection can infect the newborn's eyes and cause visual deficits
- B. The newborn is at risk for blindness from a corneal syphilitic infection acquired from a mother's infected vagina
- C. Treatment prevents tear duct obstruction with harmful exudate from a vaginal birth that can lead to dry eyes in the newborn
- D. State law mandates all newborns receive prophylactic treatment to prevent gonorrheal or chlamydial ophthalmic infection
Correct answer: D
Rationale: The correct answer is D because informing about state law emphasizes the legal requirement and public health rationale behind prophylactic eye treatment to prevent serious infections like gonorrheal or chlamydial ophthalmic infection. Choices A, B, and C are incorrect. Choice A focuses on staphylococcus infection, which is not the primary concern addressed by the prophylactic ointment. Choice B mentions a specific infection acquired from the mother's infected vagina, which is not the main reason for the ophthalmic ointment. Choice C discusses tear duct obstruction and dry eyes, which are not the primary concerns addressed by the prophylactic ointment.
3. Which client is at the highest risk for developing pressure ulcers?
- A. A 50-year-old client with a fractured femur
- B. A 30-year-old client with diabetes mellitus
- C. A 65-year-old client with limited mobility
- D. A 70-year-old client with a history of stroke
Correct answer: C
Rationale: Clients with limited mobility are at the highest risk for developing pressure ulcers due to prolonged pressure on specific areas of the body. This constant pressure can lead to tissue damage and ultimately result in pressure ulcers. While age and medical conditions such as diabetes and a history of stroke can contribute to the risk of pressure ulcers, limited mobility is the most significant factor as it directly affects the ability to shift positions and relieve pressure on vulnerable areas of the body. Therefore, the 65-year-old client with limited mobility is at the highest risk compared to the other clients. The 50-year-old client with a fractured femur may have limited mobility due to the injury, but it is temporary and may not be as prolonged as chronic limited mobility. The 30-year-old client with diabetes mellitus and the 70-year-old client with a history of stroke are at risk for developing pressure ulcers, but their conditions do not directly impact their ability to shift positions and alleviate pressure like limited mobility does.
4. The nurse is monitoring a client's intravenous infusion and observes that the venipuncture site is cool to the touch, swollen, and the infusion rate is slower than the prescribed rate. What is the most likely cause of this finding?
- A. The solution's rate is too rapid
- B. The client has phlebitis
- C. The infusion site is infected
- D. The infusion is infiltrated
Correct answer: D
Rationale: The correct answer is D. An infiltrated IV occurs when fluid leaks into the surrounding tissue, causing coolness, swelling, and a slow infusion rate. Choice A is incorrect because a rapid solution rate does not typically cause these specific symptoms. Choice B, phlebitis, presents with redness, warmth, and tenderness along the vein, not coolness. Choice C, infection, usually manifests with redness, warmth, and possibly purulent drainage, not coolness and swelling.
5. The nurse is assessing a client who has been diagnosed with chronic obstructive pulmonary disease (COPD). Which clinical finding is characteristic of this condition?
- A. Pursed-lip breathing
- B. Hyperresonance on percussion
- C. Bradycardia
- D. High-pitched inspiratory crackles
Correct answer: A
Rationale: Pursed-lip breathing is a characteristic finding in clients with COPD. It helps keep the airways open during exhalation, acting as a compensatory mechanism to prevent airway collapse, which is common in COPD. Hyperresonance on percussion is typically found in conditions like emphysema, which is a component of COPD but not characteristic of the overall disease. Bradycardia is not typical in COPD; instead, clients often exhibit tachycardia due to chronic hypoxemia. High-pitched inspiratory crackles are more commonly associated with conditions like pneumonia, not COPD.
