Correct Answer: B

Rationale: The nurse's best approach to address the patient's fear of pain is to provide accurate information about pain management strategies and options. In doing so, the nurse can help alleviate the patient's concerns by empowering them with knowledge and potential solutions for managing pain during and after the procedure. By acknowledging the patient's fear and addressing it with practical information, the nurse can build trust, reduce anxiety, and create a more supportive and collaborative environment for the patient. Dismissing, ignoring, or invalidating the patient's fear would not be effective in addressing the underlying concerns and could potentially lead to increased distress and resistance to the recommended procedure.

Correct Answer: C

Rationale: Hypokalemia (low levels of potassium) increases the risk of digoxin toxicity. This is because digoxin competes with potassium for binding sites on the sodium-potassium ATPase pump in the cell membrane. When potassium levels are low, there is an increased binding of digoxin to these pumps, leading to enhanced entry of calcium into the cells. This can result in an increased intracellular calcium concentration, leading to digoxin toxicity and potential cardiac arrhythmias. Therefore, monitoring and correcting potassium levels is crucial in patients prescribed digoxin to reduce the risk of toxicity.

Correct Answer: B

Rationale: Record-keeping is not an optional task; it is a critical aspect of professional nursing practice. As a nurse, maintaining accurate and timely records is essential for providing quality care, ensuring legal and ethical standards are met, and promoting patient safety. Failure to keep thorough records can lead to serious consequences such as compromising patient care, violating regulations, and even facing legal consequences. Thus, record-keeping should be seen as a mandatory part of the professional duty of nurses rather than an optional task that can be done when circumstances allow.

Correct Answer: A

Rationale: In the case of Romy being diagnosed with small cell lung cancer (SCLC) and undergoing palliative treatment, the most appropriate nursing action is to focus on providing relief from symptoms. Palliative care aims to improve the quality of life for patients with serious illnesses by managing their symptoms, such as pain, shortness of breath, nausea, and other side effects of treatment. As the cancer is advanced and the goal is not curative treatment but rather to keep the patient comfortable, symptom management becomes a priority to ensure Romy's physical comfort and well-being during this difficult time. Providing relief from symptoms is crucial in palliative care to help enhance the patient's quality of life and ensure they are as comfortable as possible.

Correct Answer: D

Rationale: Since Nadine is just four years old, determining her favorite toys is not a critical aspect for Nurse Alma to consider in terms of routines and rituals. While knowing Nadine's favorite toys may help provide comfort or distraction, it is not as essential as ensuring proper feeding, sleep patterns, and toilet training for a young child's well-being and development. The focus should primarily be on aspects that directly impact her physical health, growth, and daily routines at this age.
