Patient Presley who is ordered for diagnostic pelvic ultrasound asks what preparation she' 11 take. Appropriate preparations for this procedure include_________.

Correct Answer: D

Rationale: For a diagnostic pelvic ultrasound, one important preparation is to have the patient void or empty their bladder before the procedure. This allows for better visualization of the pelvic organs and structures during the ultrasound scan. A full bladder can obstruct the view and make it difficult to obtain accurate images. Therefore, it is essential for the patient to follow instructions to empty their bladder before the pelvic ultrasound to ensure the best results.

Correct Answer: C

Rationale: Battery occurs when there is an intentional harmful or offensive contact with a person without their consent. In this scenario, Nurse Edna applied a body restraint to the patient without the doctor's order, which constitutes unauthorized physical contact. The patient did not give consent for the restraint, and Nurse Edna's action could be considered battery. It is important for healthcare providers to obtain proper authorization before using any form of physical restraint on a patient to avoid legal implications such as battery.

Correct Answer: C

Rationale: Ménière's disease is characterized by the triad of symptoms including progressive sensorineural hearing loss, tinnitus, and vertigo. The audiometric testing in Ménière's disease often shows a "carrot-shaped" configuration, which refers to low-frequency hearing loss initially and eventually spreading to involve higher frequencies. This distinctive pattern of hearing loss helps differentiate Ménière's disease from other causes like Presbycusis (age-related hearing loss) or Noise-induced hearing loss. Acoustic neuroma can present with unilateral sensorineural hearing loss but typically does not exhibit the specific "carrot-shaped" configuration seen in Ménière's disease.

Correct Answer: C

Rationale: An assumption is a belief or statement that is accepted as true without proof. In this case, the statement suggests a belief that the length of service does not affect the degree of patient safety practices among staff nurses, without providing evidence or data to support this claim. It is an assumption about the relationship between two variables without a proper basis or evidence to back it up, making it an example of an assumption.

Correct Answer: A

Rationale: I. It blocks the urethra: Benign Prostatic Hyperplasia (BPH) is a condition in which the prostate gland enlarges and can squeeze the urethra, leading to urinary symptoms such as difficulty urinating. This statement correctly explains one of the effects of BPH on the urinary system.

Correct Answer: A

Rationale: The healthcare team should prioritize administering lactulose or other ammonia-lowering agents to manage hepatic encephalopathy in a patient with acute liver failure. Hepatic encephalopathy is a neuropsychiatric syndrome that occurs in patients with liver dysfunction, leading to the accumulation of ammonia and other neurotoxic metabolites in the bloodstream. Lactulose works by acidifying the colon, which promotes the conversion of ammonia to ammonium, a less toxic form that can be excreted in the stool. By reducing the levels of ammonia, lactulose helps improve the neurological symptoms associated with hepatic encephalopathy.

Correct Answer: A

Rationale: Natural killer (NK) cells play a vital role in the innate immune response by identifying and eliminating virus-infected cells, as well as tumor cells, without the need for prior exposure or activation. NK cells are able to detect abnormal cells by recognizing changes in the cell surface molecules, such as downregulation of MHC class I molecules. Once activated, NK cells release cytotoxic granules containing perforin and granzyme, leading to the destruction of the target cell. This direct killing mechanism is crucial for controlling viral infections and preventing the development of tumors. NK cells do not produce antibodies (option B), present antigens to T cells (option C), or release cytokines to recruit other immune cells (option D) as their primary function in the immune response.

Correct Answer: B

Rationale: Patient's uterine contractions lasting 70 seconds and occurring every 90 seconds signify hyperstimulation, which can be a serious complication associated with oxytocin administration. This may result in decreased uterine perfusion, fetal distress, and other adverse effects. The first action should be to discontinue the oxytocin infusion to prevent further complications and allow the uterus to relax. Observations and assessment should continue to monitor the patient's condition and response after discontinuing the infusion. Giving an emergency bolus of oxytocin or increasing the IV infusion rate would exacerbate the hyperstimulation, and turning the client to her left side and breathing deeply would not address the underlying issue of oxytocin-induced hyperstimulation.

Correct Answer: A

Rationale: A normal thyroid state is referred to as euthyroid, which means the thyroid gland is functioning within normal parameters and the levels of thyroid hormones in the body are balanced. In contrast, hyperthyroid refers to an overactive thyroid gland, causing excessive production of thyroid hormones, while parathyroid is a different gland responsible for regulating calcium levels in the body. Panthroid is not a recognized medical term related to thyroid function. Therefore, the best response to the patient's question about the normal thyroid state is "Euthyroid."
