1. What are the key signs of hyperkalemia and how should it be treated?

A. Elevated potassium levels, muscle weakness; administer calcium gluconate
B. Decreased potassium levels, confusion; administer potassium chloride
C. Elevated sodium levels, bradycardia; administer sodium bicarbonate
D. Low sodium levels, muscle cramps; administer sodium chloride

Correct answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

2. How should a healthcare professional assess a patient with suspected sepsis?

A. Monitor vital signs and administer antibiotics
B. Monitor for signs of infection and confusion
C. Monitor for fever and check oxygen saturation
D. Assess for confusion and administer fluids

Correct answer: A

Rationale: When assessing a patient with suspected sepsis, it is crucial to monitor vital signs like temperature, heart rate, respiratory rate, and blood pressure. Administering antibiotics promptly is also vital to treat the infection causing sepsis. This approach helps in preventing the progression of sepsis to severe stages and reduces the risk of complications. Choice B is incorrect because only monitoring signs of infection and confusion may delay necessary treatment with antibiotics. Choice C is incorrect as it focuses only on fever and oxygen saturation, missing other important vital signs. Choice D is incorrect because assessing for confusion alone is not sufficient, and administering fluids should be guided by the patient's fluid status rather than being an initial step in suspected sepsis assessment.

3. A client with asthma and a new prescription for an ipratropium inhaler is being taught by a nurse. Which statement by the client indicates an understanding of the teaching?

A. I will rinse my mouth after each use
B. I should wait 5 minutes before taking a second puff
C. I should take this medication when I wake up
D. I should wait 1 minute before taking a second puff

Correct answer: D

Rationale: The correct answer is D because waiting 1 minute between puffs ensures proper absorption of the medication. Choice A is incorrect as rinsing the mouth is not a specific instruction related to using the inhaler. Choice B is incorrect as waiting 5 minutes between puffs is longer than necessary. Choice C is incorrect as the timing of medication administration is not specified in the question.

4. A nurse assisting with a childbirth class is discussing nonpharmacological strategies used during labor. Which of the following statements by a client indicates an understanding of cutaneous stimulation?

A. Apply counter-pressure for back pain
B. Use deep breathing exercises
C. Visualize the baby's head
D. Use massage therapy

Correct answer: A

Rationale: The correct answer is A: 'Apply counter-pressure for back pain.' Counter-pressure involves applying pressure to the lower back to alleviate pain during labor. This technique is a form of cutaneous stimulation, which can help with pain relief. Choice B, deep breathing exercises, is a form of relaxation technique and does not directly involve cutaneous stimulation. Choice C, visualizing the baby's head, is a mental imagery technique and does not involve physical stimulation of the skin. Choice D, massage therapy, is a tactile stimulation technique but is not specifically focused on back pain relief through counter-pressure.

5. A nurse is preparing to administer insulin to a client who has type 1 diabetes mellitus. After drawing up the medication, the nurse accidentally brushes the needle on the counter's surface. Which of the following actions should the nurse take?

A. Prepare a new dose of insulin injection
B. Administer the insulin as it is
C. Wipe the needle with an alcohol swab
D. Ask the provider for guidance

Correct answer: A

Rationale: The correct action for the nurse to take is to prepare a new dose of insulin injection. Accidentally brushing the needle on a contaminated surface can lead to infection risk. Administering the insulin as it is or just wiping the needle with an alcohol swab would not be sufficient to eliminate the risk of infection. Asking the provider for guidance is not necessary in this situation as the nurse can independently take the appropriate action to ensure patient safety.
