1. What percentage of the offspring of the parents is predicted to have a cleft chin?
- A. 25%
- B. 50%
- C. 0%
- D. 75%
Correct answer: A
Rationale: When one parent carries the recessive gene for a cleft chin and the other does not, there is a 25% chance of the offspring inheriting the cleft chin. This is due to the fact that the trait follows a simple Mendelian inheritance pattern, where the offspring would need to inherit the recessive gene from both parents to express the trait. Therefore, 25% of the offspring are predicted to have a cleft chin. Choices B, C, and D are incorrect because the likelihood of inheriting a cleft chin in this specific scenario is 25%, not 50%, 0%, or 75%.
2. The nurse is caring for a client with an acute myocardial infarction. Which symptom requires immediate intervention?
- A. Dizziness
- B. Shortness of breath
- C. Severe chest pain
- D. Nausea and vomiting
Correct answer: C
Rationale: Severe chest pain is the hallmark symptom of an acute myocardial infarction (heart attack) and requires immediate intervention to prevent further damage to the heart muscle. Chest pain in this context is often described as crushing, pressure, tightness, or heaviness. It can radiate to the arms, neck, jaw, back, or upper abdomen. Other symptoms like dizziness, shortness of breath, nausea, and vomiting may also occur in acute myocardial infarction, but chest pain is the most critical sign requiring prompt action as it signifies inadequate blood flow to the heart muscle. Shortness of breath may indicate heart failure, while nausea and vomiting can be associated with the sympathetic response to myocardial infarction. Dizziness could result from decreased cardiac output but is not as specific to myocardial infarction as severe chest pain.
3. A nurse manager is reviewing the nurse’s documentation on the unit. Which of the following best describes the importance of this review?
- A. The nurse manager’s review of documentation is crucial to ensure that it meets legal and ethical standards and accurately reflects the care provided to patients.
- B. The nurse manager’s review of documentation is important to ensure that it is thorough, accurate, and reflects the nurse’s accountability for patient care.
- C. The nurse manager’s review of documentation is necessary to ensure that it is consistent with the unit’s policies and procedures and that it accurately reflects the care provided.
- D. The nurse manager’s review of documentation is essential to ensure that it meets regulatory requirements and that it supports the delivery of safe and effective patient care.
Correct answer: D
Rationale: The nurse manager's review of documentation is a critical aspect of maintaining quality patient care. Choice D is the correct answer as it highlights the importance of ensuring that documentation meets regulatory requirements, supporting the delivery of safe and effective patient care. Regulatory requirements are established to ensure that healthcare facilities function within established guidelines and standards, promoting patient safety and quality of care. Choices A, B, and C, although important aspects of documentation review, do not fully encapsulate the significant role of regulatory compliance in ensuring the overall quality and safety of patient care.
4. A client is receiving an intravenous (IV) infusion of an antineoplastic medication. During the infusion, the client complains of pain at the insertion site. The nurse notes redness and swelling at the site, along with a slowed infusion rate. What is the appropriate action for the nurse to take?
- A. Notify the healthcare provider.
- B. Administer pain medication to reduce discomfort.
- C. Apply ice and maintain the infusion rate as prescribed.
- D. Elevate the extremity of the IV site and slow the infusion rate.
Correct answer: A
Rationale: When a client complains of pain at the IV insertion site, and there are signs of extravasation such as redness and swelling, it is crucial to notify the healthcare provider immediately. Extravasation of antineoplastic medications can cause tissue damage, pain, and necrosis if they escape into surrounding tissues. Prompt action is necessary to prevent further complications and ensure appropriate management of the situation. Administering pain medication, applying ice, or elevating the extremity are not appropriate actions in cases of suspected extravasation. These actions do not address the underlying issue of potential tissue damage and necrosis that can occur due to the leakage of antineoplastic medication.
5. A client who developed syndrome of inappropriate antidiuretic hormone (SIADH) associated with small carcinoma of the lung is preparing for discharge. When teaching the client about self-management with demeclocycline (Declomycin), the nurse should instruct the client to report which condition to the healthcare provider?
- A. Insomnia
- B. Muscle cramping
- C. Increased appetite
- D. Anxiety
Correct answer: B
Rationale: The correct answer is B: Muscle cramping. SIADH causes dilutional hyponatremia due to increased ADH release. Demeclocycline is used to block the action of ADH. Muscle cramping can indicate electrolyte imbalances related to hyponatremia, which should be reported to the healthcare provider. Insomnia, increased appetite, and anxiety are not typically associated with the side effects or complications of demeclocycline or SIADH.
