Nokea
A patient presents with a pruritic, erythematous rash with edematous plaques and vesicles on the hands and fingers. The patient reports a history of exposure to detergents and frequent hand washing. Which of the following conditions is most likely responsible for this presentation?
- A. Atopic dermatitis
- B. Contact dermatitis
- C. Psoriasis
- D. Pityriasis rosea
Correct Answer: B
Rationale: The presentation of a pruritic, erythematous rash with edematous plaques and vesicles on the hands and fingers in a patient with a history of exposure to detergents and frequent hand washing is most indicative of contact dermatitis. Contact dermatitis can be caused by direct contact with irritants such as detergents or chemicals, leading to skin irritation and inflammation. In this case, the history of exposure to detergents and hand washing suggests that the rash is likely due to irritant contact dermatitis. Atopic dermatitis, psoriasis, and pityriasis rosea do not typically present with the same pattern of rash in response to irritant exposure.

Which of the following imaging test that uses transducer will be likely be ordered by the physician to detect gallstones?
- A. Computed Tomography
- B. Abdominal Ultrasound
- C. Abdominal X-ray
- D. Doppler sonography
Correct Answer: B
Rationale: An abdominal ultrasound is the imaging test that uses a transducer and is most commonly ordered by physicians to detect gallstones. This non-invasive procedure allows the physician to visualize the gallbladder and detect any presence of gallstones. The transducer emits sound waves that bounce off the gallstones, creating images that can be seen on a screen. This imaging test is safe, reliable, and effective in diagnosing gallstones without the use of radiation or contrast dye.
A patient with chronic kidney disease presents with metabolic acidosis. Which compensatory mechanism is the body most likely to employ to normalize pH?
- A. Hyperventilation
- B. Increased bicarbonate reabsorption
- C. Increased renal excretion of hydrogen ions
- D. Decreased renal excretion of bicarbonate ions
Correct Answer: B
Rationale: In a patient with chronic kidney disease presenting with metabolic acidosis, the compensatory mechanism the body is most likely to employ to normalize pH is increased bicarbonate reabsorption in the kidneys. The kidneys play a crucial role in maintaining acid-base balance by regulating bicarbonate levels in the blood. In metabolic acidosis, there is an excess of non-volatile acids in the body, leading to a decrease in blood pH. To compensate for this acidosis, the kidneys increase the reabsorption of filtered bicarbonate ions from the renal tubules back into the blood. This process helps to raise the bicarbonate levels in the blood, which in turn helps to neutralize excess hydrogen ions and restore the blood pH towards normal levels. Hyperventilation (A) is a compensatory mechanism for respiratory acidosis, not metabolic acidosis. Increased renal excretion of hydrogen ions (C) and decreased renal excretion of bicarbonate ions
Which of the following diagnostic tests is most appropriate for evaluating a woman with suspected cervical dysplasia?
- A. Pap smear
- B. Endometrial biopsy
- C. Colposcopy with biopsy
- D. Transvaginal ultrasound
Correct Answer: C
Rationale: Colposcopy with biopsy is the most appropriate diagnostic test for evaluating a woman with suspected cervical dysplasia. Colposcopy is a procedure in which a special magnifying instrument called a colposcope is used to examine the cervix for any abnormal areas. If abnormal tissue is identified during colposcopy, a biopsy will be taken to confirm the presence of cervical dysplasia and determine the severity. This allows for a more accurate diagnosis and appropriate management of the condition. Pap smear, although a screening test for cervical dysplasia, may not provide a definitive diagnosis and may require further evaluation with colposcopy and biopsy. Endometrial biopsy and transvaginal ultrasound are not indicated for evaluating cervical dysplasia specifically.
Which of the following is a common complication associated with hip fracture in elderly patients?
- A. Compartment syndrome
- B. Avascular necrosis of the femoral head
- C. Dislocation of the hip prosthesis
- D. Volkmann's contracture
Correct Answer: B
Rationale: Avascular necrosis of the femoral head, also known as osteonecrosis, is a common complication associated with hip fractures in elderly patients. It occurs when there is a loss of blood supply to the femoral head following the fracture, leading to bone tissue death. This can result in pain, limitation of motion, and potentially the collapse of the femoral head, causing further complications. Timely diagnosis and appropriate management are crucial in order to prevent further degeneration of the hip joint. Other complications such as compartment syndrome, dislocation of the hip prosthesis, and Volkmann's contracture are not typically associated with hip fractures in elderly patients.
Upon admission for an appendectomy, the patient provides the nurse with a document that specifies instructions his healthcare team should follow in the event he is unable to communicate these wishes postoperatively. This document is best known as a/an:
- A. informed consent
- B. Patient's Bill of Rights
- C. insurance card
- D. advance directive
Correct Answer: D
Rationale: An advance directive is a legal document that specifies a person's healthcare preferences and instructions for medical treatment in the event they are unable to communicate their wishes. It typically includes decisions about life-sustaining treatments, resuscitation, and end-of-life care. In the scenario provided, the document provided by the patient to the nurse outlining his healthcare team's instructions postoperatively indicates that he has an advance directive in place to guide his medical care if necessary. In contrast, informed consent is a process in which a patient gives permission for medical treatment after being informed about the risks, benefits, and alternatives. Patient's Bill of Rights outlines the patient's rights within the healthcare system, and an insurance card provides information about the patient's insurance coverage.
