A nurse is conducting a patient's history and physical examination. Which information should the nurse consider as subjective data? Which information is subjective data?
- A. Petechiae
- B. Nausea
- C. Cyanosis
- D. Fever
Correct Answer: B
Rationale: Subjective data is information provided by the patient based on their feelings, perceptions, or beliefs. Nausea falls under this category as it is a symptom that the patient experiences and reports subjectively. Petechiae, cyanosis, and fever are objective data as they can be observed or measured directly. Petechiae are small red or purple spots on the skin, cyanosis is a bluish discoloration of the skin due to lack of oxygen, and fever is an elevated body temperature, all of which can be confirmed through visual inspection or measurement. Therefore, choice B, nausea, is the correct answer as it relies on the patient's subjective experience.

A nurse is about to administer a daily dose of potassium chloride 20 mEq suspension orally. The available amount is potassium chloride suspension 10 mEq/mL. How many mL should the nurse administer? How many mL of potassium chloride should the nurse administer?
Correct Answer: 2
Rationale: To determine the amount of suspension needed, divide the desired dose (20 mEq) by the concentration (10 mEq/mL). 20 mEq ÷ 10 mEq/mL = 2 mL. This calculates the correct amount of 2 mL. Other choices are incorrect as they do not follow this calculation, leading to inaccurate dosing.
A nurse plans to leave her scheduled shift an hour early without permission or notification of the charge nurse. The patients in her assignment are stable. Which of the following legal torts applies to this situation? Which legal tort applies to leaving shift early without permission?
- A. Negligence
- B. Battery
- C. Slander
- D. Libel
Correct Answer: A
Rationale: The correct answer is A: Negligence. Leaving the shift early without permission constitutes negligence as it is a breach of the duty of care owed to the patients. The nurse has a legal responsibility to provide care for the patients until properly relieved. The other choices, Battery, Slander, and Libel, do not apply in this scenario. Battery involves intentional harmful or offensive contact without consent, Slander involves spoken defamation, and Libel involves written defamation. In this case, the nurse's actions do not align with the elements of these torts.
A nurse is preparing to administer furosemide 40 mg IV. Available is furosemide 10 mg/1 mL. How many mL should the nurse administer per dose? How many mL of furosemide should the nurse administer?
Correct Answer: 4
Rationale: The correct answer is 4 mL. To determine this, the nurse uses the formula: Desired dose (40 mg) ÷ Stock strength (10 mg/1 mL) = mL to administer. Thus, 40 mg ÷ 10 mg/1 mL = 4 mL. This calculation ensures the proper dosage is given. Other choices are incorrect because they do not follow the correct dosage calculation based on the given information.
A nurse is preparing to replace a nearly empty container of total parenteral nutrition (TPN) for a patient. There has been a delay in receiving the new TPN solution from the pharmacy. Which of the following solutions should the nurse infuse until the next TPN solution is available? Which solution should the nurse infuse during TPN delay?
- A. Lactated Ringer's.
- B. 0.9% sodium chloride.
- C. Sodium chloride.
- D. Dextrose 10% in water.
Correct Answer: D
Rationale: The correct answer is D: Dextrose 10% in water. During a delay in receiving TPN, it is important to provide a source of glucose to prevent hypoglycemia. Dextrose 10% in water provides a source of glucose for the patient. Lactated Ringer's (A) and 0.9% sodium chloride (B) are isotonic solutions but do not provide glucose. Sodium chloride (C) is a saline solution and does not provide any nutritional value. Therefore, Dextrose 10% in water is the most appropriate choice to prevent hypoglycemia in this situation.
A nurse is caring for a patient who has a new prescription for metformin. Which of the following laboratory tests should the nurse monitor? Which lab test should the nurse monitor for metformin?
- A. Liver function tests
- B. Thyroid function tests
- C. Complete blood count
- D. Renal function tests
Correct Answer: D
Rationale: The correct answer is D: Renal function tests. Metformin is primarily excreted by the kidneys, so monitoring renal function tests like serum creatinine and estimated glomerular filtration rate (eGFR) is crucial to assess kidney function and prevent potential metformin-induced lactic acidosis. Monitoring liver function tests (A) is not essential for metformin therapy, as metformin is not metabolized by the liver. Thyroid function tests (B) are not directly affected by metformin. Complete blood count (C) is not typically monitored specifically for metformin therapy. Therefore, the most appropriate choice is D as it directly reflects metformin's clearance and potential for toxicity.
