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.

A nurse is working in a pediatric clinic, and a 25-year-old mother comes in with a 4-week-old baby. The mother is stressed out about the loss of sleep, and the baby exhibits signs of colic. Which of the following techniques should the nurse teach the mother?
- A. Distraction of the infant with a red object
- B. Prone positioning techniques
- C. Tapping reflex techniques
- D. Neural warmth techniques
Correct Answer: D
Rationale: Neural warmth techniques involve the caregiver providing a warm, soothing touch to the baby, which can help to lower the baby's agitation level and promote relaxation. This technique is beneficial for calming colicky babies. Choices A, B, and C are incorrect because distraction with a red object, prone positioning, and tapping reflex techniques are not effective methods for managing colic in infants. Red object distraction is not a proven technique for soothing colicky babies. Prone positioning is not recommended for infants due to the risk of sudden infant death syndrome (SIDS). Tapping reflex techniques are not recognized as effective interventions for colic.
When encountering the significant other of a patient with end-stage AIDS crying during her smoke break, what is the most appropriate action for the nurse to take?
- A. Allow her to grieve by herself.
- B. Tell her to go ahead and cry, after all, your husband’s pretty bad off.
- C. Tell her you realize how upset she is, but you don’t want to talk about it now.
- D. Approach her, offering tissues, and encourage her to verbalize her feelings
Correct Answer: D
Rationale: Approaching the significant other, offering tissues, and encouraging her to verbalize her feelings is the most appropriate action for the nurse to take. Being left alone during the grief process isolates individuals, and they need an outlet for their feelings. By showing empathy and providing support, the nurse can help the significant other cope with her emotions. Choices A, B, and C are inappropriate because they do not offer support or encourage the expression of feelings, which are crucial in such situations.
A healthcare professional is reviewing a patient's ECG report. The patient exhibits a flat T wave, depressed ST segment, and short QT interval. Which of the following medications can cause all of the above effects?
- A. Morphine
- B. Atropine
- C. Procardia
- D. Digitalis
Correct Answer: D
Rationale: The correct answer is Digitalis. Digitalis is known to cause a flat T wave, depressed ST segment, and a short QT interval on an ECG report. These ECG changes are characteristic of digitalis toxicity. Morphine is not typically associated with these ECG changes. Atropine is more commonly linked to increasing heart rate rather than causing these specific ECG abnormalities. Procardia is a calcium channel blocker that does not typically produce the described ECG findings. Therefore, Digitalis is the most likely medication causing these effects in the patient.
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 client who has a known history of cardiac problems and is still smoking enters the clinic complaining of sudden onset of sharp, stabbing pain that intensifies with a deep breath. The pain is occurring on only one side and can be isolated upon general assessment. The nurse concludes that this description is most likely caused by:
- A. pleurisy.
- B. pleural effusion.
- C. atelectasis.
- D. tuberculosis.
Correct Answer: A
Rationale: Pleurisy is an inflammation of the pleura and is often accompanied by an abrupt onset of pain. Symptoms of pleurisy include sudden sharp, stabbing pain that is usually unilateral and localized to a specific portion of the chest. The pain can be exacerbated by deep breathing. In contrast, pleural effusion is characterized by fluid accumulation in the pleural space, not sharp pain. Atelectasis involves collapse or closure of a lung leading to reduced gas exchange, but it does not typically present with sharp, stabbing pain. Tuberculosis is a bacterial infection that can affect the lungs but does not typically manifest with sudden sharp pain exacerbated by deep breathing.
