Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?
- A. Radiation
- B. Conduction
- C. Convection
- D. Evaporation
Correct Answer: B
Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy.
Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.

Which of the following is NOT a terminal learning objective for Phase I of the M6 Practical Nurse Course?
- A. Identify principles of basic-level anatomy, physiology, microbiology, and nutrition
- B. Perform basic-level pharmacological calculations
- C. Integrate the knowledge of drug therapy into nursing practice
- D. Identify basic principles of field nursing
Correct Answer: C
Rationale: The correct answer is C. Integrating drug therapy knowledge is not a terminal learning objective for Phase I of the M6 Practical Nurse Course. Phase I typically focuses on foundational knowledge and skills, such as understanding basic-level anatomy, physiology, microbiology, and nutrition (Choice A), performing basic-level pharmacological calculations (Choice B), and identifying basic principles of field nursing (Choice D). While drug therapy knowledge is important in nursing practice, it is not a specific terminal learning objective for Phase I of this course.
The client diagnosed with acute pancreatitis has developed a pseudocyst that ruptures. Which procedure should the nurse anticipate the HCP ordering?
- A. Paracentesis
- B. Chest tube insertion
- C. Lumbar puncture
- D. Biopsy of the pancreas
Correct Answer: B
Rationale: The correct answer is B: Chest tube insertion. In the context of a pancreatic pseudocyst rupturing, a chest tube may be needed if the pseudocyst extends into the pleural space, leading to a pleural effusion. Choice A, paracentesis, involves the removal of fluid from the abdominal cavity, not the pleural space. Choice C, lumbar puncture, is a procedure performed to collect cerebrospinal fluid from the spinal canal, not relevant in this scenario. Choice D, biopsy of the pancreas, is not indicated in the immediate management of a ruptured pseudocyst.
Which nursing instruction should the nurse discuss with the client who is receiving glucocorticoids for Addison's disease?
- A. Discuss the importance of tapering medications when discontinuing medication
- B. Explain that the dose will need to be decreased during times of stress or infection
- C. Instruct the client to take medication on an empty stomach with a glass of water
- D. Encourage the client to wear a MedicAlert bracelet and carry a card in the wallet
Correct Answer: A
Rationale: The correct answer is A because tapering glucocorticoids is crucial to prevent adrenal insufficiency, which can occur if the medication is stopped abruptly. Choice B is incorrect as it refers to dose adjustments during stress or infection, not discontinuation. Choice C is incorrect because it does not specifically address the issue of stopping the medication. Choice D is not directly related to the management of glucocorticoid therapy for Addison's disease.
The nurse prepares to administer digoxin (Lanoxin) to a newborn with a diagnosis of heart failure and notes that the apical rate is 140 beats per minute. Which nursing action is appropriate?
- A. Hold the medication
- B. Administer the digoxin
- C. Notify the healthcare provider
- D. Recheck the apical rate in 1 hour
Correct Answer: B
Rationale: An apical rate of 140 bpm is within the normal range for a newborn. Digoxin is commonly used to treat heart failure by increasing the strength and efficiency of the heart's contractions. Since the heart rate is within the normal range, there is no need to hold the medication or notify the healthcare provider. Rechecking the apical rate in an hour is unnecessary as the heart rate is not alarming. Therefore, the appropriate nursing action is to administer the digoxin.
Which intervention should the nurse implement for the client who has an ileal conduit?
- A. Pouch the stoma with a one-inch margin around the stoma
- B. Refer the client to the United Ostomy Association for discharge teaching
- C. Report to the healthcare provider any decrease in urinary output
- D. Monitor the stoma for signs and symptoms of infection every shift
Correct Answer: C
Rationale: The correct intervention for a client with an ileal conduit is to report to the healthcare provider any decrease in urinary output. A decrease in urinary output can be indicative of a blockage or other complication, necessitating immediate attention. Choice A is incorrect because pouching the stoma with a margin around it is not directly related to managing complications. Choice B is incorrect as referring the client to an ostomy association may be beneficial for education but is not the immediate action needed for decreased urinary output. Choice D is incorrect because monitoring for infection, although important, is not the priority when dealing with a potential complication like decreased urinary output.
