When teaching a patient with COPD pulmonary exercises, what should be done?
- A. Teach pursed-lip breathing techniques.
- B. Encourage repetitive heavy lifting exercises to increase strength.
- C. Limit exercises due to respiratory acidosis.
- D. Take breaks every 10-20 minutes during exercises.
Correct Answer: A
Rationale: The correct answer is to teach pursed-lip breathing techniques. Pursed-lip breathing helps to decrease the volume of air expelled by keeping the airways open longer, making it easier for patients with COPD to breathe out. Encouraging heavy lifting exercises (Choice B) is not suitable for patients with COPD as it can lead to increased shortness of breath. Limiting exercises due to respiratory acidosis (Choice C) is not correct; instead, exercises should be tailored to the patient's tolerance. Taking breaks every 10-20 minutes (Choice D) is not specific to the management of COPD pulmonary exercises.

Which instruction should be given in a health education class regarding testicular cancer?
- A. All males should perform a testicular exam after a warm bath or shower.
- B. Testicular exams should be performed on a daily basis.
- C. Reddening or darkening of the scrotum is a normal finding.
- D. Testicular exams should be performed after a warm bath or shower.
Correct Answer: D
Rationale: The correct instruction for testicular cancer education is that testicular exams should be performed after a warm bath or shower as it relaxes the scrotum and makes the exam easier. Testicular exams should be done monthly by all men starting around age 15, not after the age of 30 (Choice A) or on a daily basis (Choice B), which is unnecessary and may lead to unnecessary anxiety. Reddening or darkening of the scrotum is not a normal finding (Choice C) and should be reported to a healthcare provider for further evaluation.
A client receiving drug therapy with furosemide and digitalis requires careful observation and care. In planning care for this client, the nurse should recognize that which of the following electrolyte imbalances is most likely to occur?
- A. hyperkalemia
- B. hypernatremia
- C. hypokalemia
- D. hypomagnesemia
Correct Answer: C
Rationale: When a client is receiving drug therapy with furosemide and digitalis, the nurse should anticipate the development of hypokalemia due to the potassium-wasting effects of furosemide. Hypokalemia can potentiate digitalis toxicity. While hyperkalemia is a concern with some medications, it is not typically associated with furosemide and digitalis. Furosemide can lead to hyponatremia, not hypernatremia, due to its diuretic effect. Hypomagnesemia, though a possible imbalance, is not the most likely to occur in this scenario as furosemide and digitalis are more commonly associated with hypokalemia.
The factor that most determines drug distribution is:
- A. vascular perfusion of the tissue or organ.
- B. salt form.
- C. drug interactions.
- D. steady state.
Correct Answer: A
Rationale: The correct answer is 'vascular perfusion of the tissue or organ.' Drug distribution is primarily determined by how well the circulatory system delivers the drug to various tissues and organs. Adequate perfusion ensures proper distribution of the drug throughout the body. While the salt form (choice B), drug interactions (choice C), and steady state (choice D) can influence drug efficacy and metabolism, they are not as crucial as vascular perfusion for the initial distribution of a drug.
A 14-year-old boy has been admitted to a mental health unit for observation and treatment. The boy becomes agitated and starts yelling at nursing staff members. What should the nurse's first response be?
- A. Create an atmosphere of seclusion for the boy according to procedures.
- B. Remove other patients from the area for added safety.
- C. Ask the patient, "What is making you mad?"?
- D. Ask the patient, "Why are you behaving this way? Have you thought about what may help you calm down?"?
Correct Answer: A
Rationale: In a situation where a patient is agitated and yelling, the first response should be to create an atmosphere of seclusion for the safety of the patient and others. Seclusion is a standard procedure to help manage aggressive behaviors and prevent harm. Options B, C, and D are not appropriate in this scenario. Removing other patients may not address the immediate safety concern, asking the patient what is making them mad can escalate the situation, and questioning why the patient is behaving that way may not help in managing the current agitation. Therefore, seclusion is the recommended course of action in this scenario to ensure the safety and well-being of all involved.
A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?
- A. Depressed function of the CNS
- B. Increased blood flow
- C. Decreased venous capacity
- D. Pain relief
Correct Answer: C
Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.
