1. A client who has been newly diagnosed with diabetes mellitus has been stabilized with daily insulin injections. Which information should the nurse teach when carrying out plans for discharge?
- A. Keep insulin vials refrigerated at all times.
- B. Rotate the insulin injection sites systematically.
- C. Increase the amount of insulin before unusual exercise.
- D. Monitor the urine acetone level to determine the insulin dosage.
Correct answer: B
Rationale: When a client is stabilized with daily insulin injections, it is crucial to rotate the injection sites systematically. This practice helps prevent the development of lipodystrophy, which can affect insulin absorption and lead to inconsistent glucose control. Additionally, rotating sites minimizes discomfort and tissue damage, ensuring optimal insulin delivery and effectiveness.
2. What is the most common symptom of gastroesophageal reflux disease (GERD)?
- A. Heartburn.
- B. Nausea.
- C. Abdominal pain.
- D. Vomiting.
Correct answer: A
Rationale: The correct answer is A: Heartburn. Heartburn is the most common symptom of GERD as it occurs due to the reflux of stomach acid into the esophagus. This leads to a burning sensation in the chest that can worsen after eating, lying down, or bending over. Choice B, Nausea, is not typically the most common symptom of GERD, although it can occur in some cases. Choice C, Abdominal pain, is not a primary symptom of GERD and is more commonly associated with other gastrointestinal conditions. Choice D, Vomiting, is also not the most common symptom of GERD, although it can occur in severe cases or as a result of complications.
3. IV potassium chloride (KCl) 60 mEq is prescribed for the treatment of a patient with severe hypokalemia. Which action should the nurse take?
- A. Administer the KCl as a rapid IV bolus.
- B. Infuse the KCl at a rate of 10 mEq/hour.
- C. Only give the KCl through a central venous line.
- D. Discontinue cardiac monitoring during the infusion.
Correct answer: B
Rationale: The correct action for the nurse to take is to infuse the KCl at a rate of 10 mEq/hour. Rapid IV infusion of KCl can lead to cardiac arrest due to its potential for causing hyperkalemia. While KCl can be administered through peripheral veins, central venous lines are not necessary unless specified. It is crucial to continue cardiac monitoring during potassium infusion to promptly identify and manage any potential dysrhythmias that may occur.
4. A patient is admitted to the hospital for treatment of pneumonia after complaining of high fever and shortness of breath. The patient was not able to produce sputum for a culture. The nurse will expect the patient’s provider to order
- A. a broad-spectrum antibiotic.
- B. a narrow-spectrum antibiotic.
- C. multiple antibiotics.
- D. the pneumococcal vaccine.
Correct answer: A
Rationale: In this scenario where the offending organism causing pneumonia is unknown due to the inability to produce sputum for culture, the appropriate choice is a broad-spectrum antibiotic. Broad-spectrum antibiotics are effective against a wide range of bacteria and are commonly used when the specific pathogen is unidentified. Narrow-spectrum antibiotics target specific types of bacteria and are chosen based on culture and sensitivity results. Using multiple antibiotics without a clear indication from culture and sensitivity testing can lead to antibiotic resistance and is not recommended in this situation. Additionally, the pneumococcal vaccine is preventive and does not treat an ongoing infection like pneumonia.
5. What is the main purpose of the working phase of the nurse-patient relationship?
- A. Establish a formal or informal contract that addresses the patient's problems.
- B. Implement nursing interventions that are designed to achieve expected patient outcomes.
- C. Develop rapport and trust so the patient feels supported, and the initial plan can be identified.
- D. Clearly identify the role of the nurse and establish the parameters of the professional relationship.
Correct answer: B
Rationale: The main purpose of the working phase in the nurse-patient relationship is to implement nursing interventions that are specifically tailored to achieve the expected patient outcomes. During this phase, the nurse actively works with the patient to put the care plan into action and make progress towards reaching the desired health goals. It involves the application of therapeutic communication, problem-solving, and interventions to address the patient's needs. Establishing rapport and trust is typically done in the orientation phase, while defining roles and boundaries usually occurs in the introductory phase of the relationship. Choices A, C, and D are incorrect as they describe activities more aligned with other phases of the nurse-patient relationship, such as orientation and introductory phases.
