Correct Answer: B

Rationale: The correct instruction for a client with myasthenia gravis prescribed pyridostigmine (Mestinon) is to take the medication 30 minutes before meals. This timing is crucial as it helps improve muscle strength for eating and swallowing. By taking the medication before meals, the client can experience enhanced muscle function during mealtime, which is especially important for managing the symptoms of myasthenia gravis.

Correct Answer: B

Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which can lead to an increased risk of bleeding. To minimize this risk, patients with thrombocytopenia should avoid activities that can cause injury or bleeding, such as intramuscular injections. Encouraging light exercise can be beneficial, as it promotes circulation without increasing the risk of trauma. Aspirin should be avoided as it can further impair platelet function. Additionally, using a soft toothbrush for oral care is recommended to prevent gum bleeding in patients with thrombocytopenia.

Correct Answer: A

Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Oral hypoglycemic agents are not appropriate in the acute setting of DKA as they may not work quickly enough. Sodium bicarbonate may be used in some cases to correct acidosis, but insulin administration takes precedence. Providing a high-calorie diet is not appropriate initially in DKA management, as the focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.

Correct Answer: C

Rationale: When a patient with cervical cancer is receiving external-beam radiation, the radiation to the abdomen can affect organs in its path, such as the bowel, leading to complications like frequent diarrhea. Cleaning the perianal area carefully after each bowel movement is crucial to decrease the risk of skin breakdown and infection. Testing stools for blood is not necessary since inflammation associated with radiation may lead to occult blood in stools. Maintaining a low-residue diet is actually recommended to prevent bowel irritation. Radiation to the abdomen does not cause stomatitis, so inspecting the mouth and throat for thrush is not directly related to the effects of external-beam radiation in this context.

Correct Answer: C

Rationale: The High Fowler's position is the most appropriate position for a patient with COPD experiencing severe dyspnea. This position helps improve lung expansion and reduce dyspnea by allowing the diaphragm to move more freely and increasing the efficiency of breathing. It also helps reduce the work of breathing and enhances oxygenation in patients with COPD.
