Correct Answer: A

Rationale: The correct answer is A: Administer pain relief. The nurse should address the client's immediate symptom of severe headache to provide comfort and assess the severity of the condition. Pain relief can help decrease anxiety and prevent complications. Monitoring vital signs (B) is important but treating the symptom should take priority. Monitoring ECG (C) is not necessary for a headache presentation. Administering insulin (D) is not indicated for a client presenting with a severe headache.

Correct Answer: B

Rationale: The correct answer is A: Eggs. Eggs are considered a complete protein because they contain all 9 essential amino acids required by the human body. This makes them a high-quality protein source. Corn (B), peanuts (C), and sunflower seeds (D) are not complete proteins as they lack one or more of the essential amino acids. Corn is deficient in lysine, peanuts are deficient in methionine, and sunflower seeds are deficient in lysine. Therefore, only eggs provide all the essential amino acids necessary for optimal health and proper bodily functions.

Correct Answer: B

Rationale: The correct answer is B: Sedation. Cancer patients taking opioids commonly experience sedation due to the central nervous system depressant effects of opioids. Opioids can cause drowsiness, fatigue, and decreased alertness. Tolerance (A) is a possible issue but is not the most common complication. Addiction (C) is less common in cancer patients due to the nature of their pain management. Constipation (D) is a common side effect of opioids but is not the most common complication in cancer patients. Sedation is the most prevalent issue affecting the quality of life and daily functioning of cancer patients on opioids.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. Bronchodilators help to relax and open up the airways, which can alleviate shortness of breath and chest tightness in conditions like asthma or COPD. Administering oxygen (choice B) can help if the client is hypoxic, but it does not directly address the underlying airway constriction. Applying a cold compress (choice C) may provide some comfort but will not address the respiratory distress. Administering IV antibiotics (choice D) is not indicated for shortness of breath and chest tightness unless there is an underlying bacterial infection.

Correct Answer: A

Rationale: The correct answer is A: Immobilize the spine. This is the first priority because it helps prevent further injury to the spinal cord. By immobilizing the spine, the nurse ensures that any movement doesn't worsen the existing injury. Placing the client in a supine position (B) can be done after immobilization. Administering analgesics (C) should not be done before assessing the extent of the injury. Assessing the airway (D) is important but should come after immobilizing the spine to prevent any unnecessary movement.
