Correct Answer: B

Rationale: The correct answer is B: Amenorrhea. Danazol is a synthetic steroid used to treat fibrocystic breast disease by suppressing ovulation and hormonal fluctuations. This leads to a decrease in menstrual bleeding, resulting in amenorrhea. Nausea and confusion are not common adverse reactions of danazol. Hypotension is also not associated with danazol use. In summary, amenorrhea is the expected side effect due to the drug's mechanism of action, making it the correct choice compared to the other options.

Correct Answer: A

Rationale: The correct answer is A: Diagnosis. After reviewing the patient's database and identifying concerning findings such as abnormal kidney function, lack of voiding, and decreased oral intake, the nurse needs to move to the diagnosis step of the nursing process. This involves analyzing the data collected to identify the patient's health problems and risks. In this case, the nurse needs to determine potential underlying issues related to the kidney function abnormalities and lack of voiding, and formulate a nursing diagnosis based on the findings. Summary of other choices: B: Planning comes after diagnosis and involves setting goals and creating a plan of care. C: Implementation follows planning and involves carrying out the plan of care. D: Evaluation is the final step of the nursing process where the nurse assesses the effectiveness of the interventions implemented.

Correct Answer: C

Rationale: The correct answer is C: Eating. Chewing food can trigger trigeminal nerve pain due to the movement and pressure applied on the nerve. The other choices (A: Sleeping, B: Reading, D: Cooking) do not involve the same level of jaw movement and pressure on the trigeminal nerve, thus are less likely to aggravate the pain. Therefore, eating is the most likely action to worsen trigeminal neuralgia symptoms in this scenario.

Correct Answer: D

Rationale: The correct answer is D because drawing up clear insulin first when mixing two types of insulin in one syringe prevents contamination. Clear insulin is drawn up first to avoid clouding from the cloudy insulin. This ensures accurate dosing and prevents potential medication errors. A: Incorrect. Administering insulin after the first meal may lead to hypoglycemia if the client skips or delays meals. B: Incorrect. Insulin should not be injected into the deltoid muscle as it can lead to inconsistent absorption rates. C: Incorrect. Vigorously shaking the insulin vial can cause bubbles, affecting the accuracy of the dose and potentially altering its effectiveness.

Correct Answer: C

Rationale: The correct answer is C: Romberg’s test. Romberg’s test assesses a patient's ability to maintain balance with eyes closed, relying on proprioception from the lower limbs. A lumbar injury can affect proprioception, leading to impaired balance. Rhine’s test evaluates auditory function, not affected by a lumbar injury. Pupillary reaction assesses cranial nerve function, unrelated to a lumbar injury. The patellar reflex is a deep tendon reflex, primarily involving the spinal cord segments L2-L4, not directly affected by a lumbar injury.
