1. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
- A. Monitor serum calcium levels.
- B. Monitor serum potassium levels.
- C. Monitor serum sodium levels.
- D. Monitor serum magnesium levels.
Correct answer: B
Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
2. A client with a history of alcoholism is admitted with confusion and ataxia. The LPN/LVN recognizes that these symptoms may be related to a deficiency in which vitamin?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin B1 (Thiamine)
Correct answer: D
Rationale: The correct answer is Vitamin B1 (Thiamine). Vitamin B1 deficiency, also known as Thiamine deficiency, is common in clients with a history of alcoholism. Thiamine is essential for proper brain function, and its deficiency can lead to neurological symptoms such as confusion and ataxia. Vitamin A, C, and D deficiencies do not typically present with confusion and ataxia in the context of alcoholism. Vitamin A deficiency mainly affects vision, Vitamin C deficiency leads to scurvy with symptoms like bleeding gums, and Vitamin D deficiency is associated with bone disorders. Therefore, they are not the correct choices in this scenario.
3. What is the first step a healthcare professional should take when preparing to provide tracheostomy care?
- A. Perform hand hygiene
- B. Gather equipment
- C. Explain the procedure
- D. Assess the client
Correct answer: A
Rationale: Performing hand hygiene is the initial step a healthcare professional should take when preparing to provide tracheostomy care. This step is crucial to prevent the transmission of pathogens and reduce the risk of infection to the client. By cleansing the hands, the healthcare professional ensures patient safety. While gathering equipment, explaining the procedure, and assessing the client are essential components of tracheostomy care, they should occur after performing hand hygiene to maintain aseptic technique and minimize the risk of introducing harmful microorganisms to the client.
4. A post-op nurse has an indwelling catheter in place for gravity drainage. The nurse notes that the client's urine bag has been empty for 2 hours. The first action the nurse should take is to:
- A. Check to see if the tubing is kinked.
- B. Increase the IV fluid rate.
- C. Check the catheter insertion site.
- D. Contact the healthcare provider.
Correct answer: A
Rationale: The correct action for the nurse to take when the urine bag has not filled for 2 hours is to check if the tubing is kinked. Kinks in the tubing can obstruct the flow of urine from the catheter, leading to decreased drainage. Increasing the IV fluid rate is not the appropriate initial action in this situation as the primary concern is with the catheter drainage. Checking the catheter insertion site would be secondary to ensuring proper drainage. Contacting the healthcare provider is not necessary as the issue can often be resolved by checking for simple tubing obstructions first.
5. When parents call the emergency room to report that a toddler has swallowed drain cleaner, the nurse instructs them to call for emergency transport to the hospital. While waiting for an ambulance, what substance should the nurse suggest the parents give the child sips of?
- A. Tea
- B. Water
- C. Milk
- D. Soda
Correct answer: B
Rationale: The correct answer is B: Water. Giving sips of water can help dilute the drain cleaner while waiting for emergency transport, which may help reduce the potential harm caused by the ingestion. Choices A, C, and D are incorrect because tea, milk, and soda can interact with the chemicals in the drain cleaner or increase the risk of vomiting, which is not recommended in this situation.
