Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. After a craniotomy, the client may experience decreased oxygen levels due to the surgical procedure, anesthesia, or potential complications. Administering oxygen helps ensure adequate oxygenation to the brain and tissues. Placing the client in a supine or Trendelenburg position can increase intracranial pressure, which is contraindicated post-craniotomy. Monitoring for arrhythmias is important, but ensuring oxygenation takes precedence as hypoxia can have immediate detrimental effects on brain function.

Correct Answer: B

Rationale: Rationale: 1. GERD: Lying down after eating can worsen symptoms due to acid reflux. Sitting up helps prevent acid reflux. 2. Dumping Syndrome: Lying down can exacerbate symptoms like nausea and dizziness. Sitting up aids in digestion. 3. Choice B recommends lying down 1 hour after eating for Dumping Syndrome and sitting up at least 30 minutes after eating for GERD, which aligns with the management of both conditions. Summary: - Choice A is incorrect as lying flat after meals worsens GERD and Dumping Syndrome symptoms. - Choice C is incorrect as sitting up only after meals does not address the specific needs of GERD and Dumping Syndrome. - Choice D is incorrect as lying down after meals is not recommended for either condition.

Correct Answer: C

Rationale: The correct answer is C: perimenopause. Perimenopause is the transitional period before menopause when a woman's body begins to produce less estrogen. This can lead to irregular menstrual cycles and other symptoms such as hot flashes, night sweats, and mood changes. Assessing for symptoms of perimenopause in a woman reporting irregular menses for six months is appropriate as it aligns with the timing and characteristics of this phase. Explanation for incorrect choices: A: Climacteric refers to the period of menopausal transition and is not specific to the symptoms mentioned in the scenario. B: Menopause is the cessation of menstrual periods for 12 consecutive months and is not typically associated with irregular menses. D: Postmenopause is the period after menopause has been established for at least 12 months and irregular menses would not be expected during this phase.

Correct Answer: B

Rationale: The correct answer is B: Provide cooling measures. When caring for a client with hyperthermia, the nurse's priority is to lower the body temperature to prevent further complications. Providing cooling measures such as removing excess clothing, using fans, applying cool compresses, and encouraging hydration helps to reduce the body temperature effectively. Administering antipyretics (A and D) may be considered in some cases, but cooling measures are more immediate and effective. Administering corticosteroids (C) is not indicated in the treatment of hyperthermia. Cooling measures directly target the elevated body temperature, making it the top priority in managing hyperthermia.

Correct Answer: D

Rationale: The correct answer is D: cirrhosis. Cirrhosis leads to impaired liver function, causing the liver to be unable to effectively metabolize ammonia, leading to high ammonia levels in the blood. Renal failure (choice A) is associated with high creatinine levels, not ammonia. Psoriasis (choice B) is a skin condition unrelated to ammonia levels. Lupus (choice C) is an autoimmune disease affecting various organs, not directly linked to high ammonia levels. In summary, cirrhosis is the only condition among the options that directly impacts liver function and can lead to high ammonia levels in the blood.
