A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?
- A. Blood pressure
- B. Heart rate
- C. Respiratory rate
- D. Oxygen saturation
Correct Answer: B
Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.

A client is admitted to the hospital with second and third degree burns to the face and neck. How should the nurse best position the client to maximize function of the neck and face and prevent contracture?
- A. The neck extended backward using a rolled towel behind the neck
- B. Prone position using pillows to support both arms outward from the torso
- C. Side-lying position using pillows to support the abdomen and back
- D. The neck forward using pillows under the head and sandbags on both sides
Correct Answer: D
Rationale: After sustaining burns to the face and neck, positioning is crucial to maintain functional posture, reduce pain, and prevent contractures. Placing the neck forward using pillows under the head and sandbags on both sides is the best option in this scenario. This position helps prevent neck and facial contractures, allowing for optimal function and healing. Choices A, B, and C do not adequately address the specific needs of a client with burns to the face and neck. Choice A could potentially exacerbate neck contractures, Choice B focuses on arm support rather than neck and face positioning, and Choice C does not directly address the needs of the burned face and neck, making them less effective in preventing contractures in these critical areas.
A client with a history of chronic back pain is prescribed oxycodone for pain management. What is the most important instruction the nurse should provide?
- A. Take the medication with food to reduce stomach upset
- B. Avoid operating heavy machinery while taking this medication
- C. Increase physical activity to enhance pain relief
- D. Report any signs of respiratory depression immediately
Correct Answer: D
Rationale: The correct answer is D: 'Report any signs of respiratory depression immediately.' Respiratory depression is a severe side effect of opioids like oxycodone and can be life-threatening. It is crucial for the nurse to instruct the client to report any signs such as slow or shallow breathing, difficulty breathing, or confusion. Choice A is incorrect as taking oxycodone with or without food does not significantly affect its efficacy. Choice B is incorrect because avoiding driving is important due to the potential impairment caused by oxycodone, but reporting respiratory depression is more critical. Choice C is incorrect as increasing physical activity may not always be suitable for individuals with chronic back pain and is not directly related to preventing respiratory depression.
A client who has just been diagnosed with tuberculosis (TB) is being discharged home. Which instruction is most important for the nurse to provide?
- A. Avoid close contact with others until treatment is complete
- B. Take all prescribed medications as directed
- C. Schedule a follow-up appointment with the healthcare provider
- D. Wear a mask when in public places
Correct Answer: B
Rationale: The correct answer is B: 'Take all prescribed medications as directed.' This instruction is the most important because adherence to the prescribed medication regimen is crucial in treating tuberculosis effectively and preventing the development of drug-resistant TB. While choice A is important for infection control, ensuring treatment adherence through proper medication intake takes precedence. Choice C is also essential for monitoring progress but is not as critical as ensuring medication compliance. Choice D is relevant for preventing transmission but is not as crucial as ensuring proper treatment by taking medications as directed.
A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?
- A. Serum glucose of 180 mg/dL
- B. Blood pH of 7.30
- C. Positive urine ketones
- D. Serum bicarbonate of 25 mEq/L
Correct Answer: C
Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.
A hospitalized toddler who is recovering from a sickle cell crisis holds a toy and says, 'Mine.' According to Erikson's theory of psychosocial development, this child's behavior is a demonstration of which developmental stage?
- A. Autonomy vs. Shame and Doubt
- B. Industry vs. Inferiority
- C. Initiative vs. Guilt
- D. Trust vs. Mistrust
Correct Answer: A
Rationale: The toddler's behavior of asserting possession ('Mine') reflects a desire for independence, aligning with Erikson's stage of Autonomy vs. Shame and Doubt. This stage, typical for toddlers aged 1-3 years, focuses on developing a sense of control and independence. Choices B, C, and D are incorrect: Industry vs. Inferiority relates to middle childhood, Initiative vs. Guilt pertains to preschoolers, and Trust vs. Mistrust is associated with infancy.
