Correct Answer: B

Rationale: Tilt back Claudia's head slightly would have been the correct action to prevent her from blinking during eye drop instillation. By tilting her head back, you create a more stable position for instilling the eye drops, reducing the likelihood of accidental contact with her eyelid. Additionally, tilting the head back slightly helps in making it easier for the drops to enter the eye and stay within the conjunctival sac, improving the efficacy of the medication.

Correct Answer: A

Rationale: The described presentation is classic for acute angle-closure glaucoma. This condition is characterized by sudden-onset severe eye pain, headache, nausea, and vomiting. The red eye, steamy cornea (corneal edema), and mid-dilated non-reactive pupil are consistent with acute angle-closure glaucoma. The sudden increase in intraocular pressure leads to impaired aqueous humor outflow, causing these symptoms. Immediate intervention is required to prevent permanent vision loss in such cases. Central retinal artery occlusion would present with sudden painless vision loss. Optic neuritis typically presents with vision loss and pain with eye movements. Corneal ulcer presents with eye discomfort, foreign body sensation, and may have a history of corneal trauma or contact lens wear.

Correct Answer: C

Rationale: Choosing option C, asking the patient about their cultural beliefs and preferences related to pain, demonstrates cultural competence in pain assessment. Pain experiences can vary greatly across different cultures, and a patient's cultural background can influence how they perceive and express pain. By inquiring about the patient's cultural beliefs and preferences, the nurse can gain a better understanding of the patient's perspective on pain. This information is crucial for providing individualized and culturally sensitive pain management interventions. It also shows respect for the patient's unique cultural background and helps build a trusting and collaborative relationship between the nurse and the patient.

Correct Answer: C

Rationale: The salivary glands are responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates. Saliva contains enzymes that begin the digestive process by breaking down carbohydrates into simpler sugars. The liver is involved in the production of bile, which aids in the digestion and absorption of fats. The gallbladder stores bile produced by the liver, which is released into the small intestine. The pancreas produces digestive enzymes that are released into the small intestine to aid in the digestion of proteins, fats, and carbohydrates.

Correct Answer: B

Rationale: Goiter is a condition characterized by the enlargement of the thyroid gland. The most common cause of goiter worldwide is iodine deficiency, which is required for the production of thyroid hormones. When there is insufficient iodine intake, the thyroid gland enlarges in an attempt to produce more hormones, leading to the development of goiter. While other factors can also contribute to the development of goiter, such as autoimmune diseases and certain medications, the primary cause associated with the condition is an iodine-deficient diet.
