1. Which of these statements is true regarding the use of Standard Precautions in the healthcare setting?
- A. Standard Precautions apply to all body fluids, except sweat.
- B. Alcohol-based hand rub should be used if hands are not visibly dirty.
- C. Standard Precautions are intended for use with all patients, regardless of their risk or presumed infection status.
- D. Standard Precautions are to be used only when non-intact skin, excretions containing visible blood, or expected contact with mucous membranes are present.
Correct answer: Standard Precautions are intended for use with all patients, regardless of their risk or presumed infection status.
Rationale: Standard Precautions are designed to reduce the risk for transmission of microorganisms from both recognized and unrecognized sources. They are intended for use with all patients, regardless of their risk or presumed infection status. Standard Precautions apply to all body fluids, secretions, and excretions except sweat – whether or not they contain visible blood, non-intact skin, or mucous membranes. Hands should be washed with soap and water if visibly soiled with blood or body fluids. Alcohol-based hand rubs can be used if hands are not visibly soiled. Choice A is incorrect because Standard Precautions apply to all body fluids, secretions, and excretions except sweat. Choice B is incorrect because alcohol-based hand rub should be used when hands are not visibly dirty. Choice D is incorrect because Standard Precautions are not limited to situations involving non-intact skin, excretions with visible blood, or expected mucous membrane contact.
2. For a healthcare worker under normal conditions with unsoiled hands, effective hand hygiene between patients requires which of the following?
- A. At least a 15-second scrub with plain soap and water
- B. At least a 23-minute scrub with an antimicrobial soap
- C. Use of an alcohol-based antiseptic hand-rub
- D. Wearing a mask when scrubbing
Correct answer: C: Use of an alcohol-based antiseptic hand-rub
Rationale: Effective hand hygiene between patients for a healthcare worker with unsoiled hands involves using an alcohol-based antiseptic hand rub. This method is sufficient for cleaning hands that are not visibly soiled. The use of an antimicrobial soap or a prolonged scrubbing time is unnecessary and not recommended in this scenario. Wearing a mask is not required for routine hand hygiene and does not contribute to effective hand cleaning.
3. A healthcare professional is preparing to administer a dose of platelets to a client. Which of the following actions must the healthcare professional perform before giving the platelets?
- A. Start an IV of 0.9% Normal Saline to administer with the platelets
- B. Ensure the container with the platelets is intact and not damaged
- C. Verify the client's identity using two unique identifiers
- D. Check the client's chart to ensure no contraindications to platelet transfusion
Correct answer: Ensure the container with the platelets is intact and not damaged
Rationale: Before administering platelets, it is crucial to check the integrity of the container holding the blood product. An intact container ensures the sterility and safety of the platelets, minimizing the risk of contamination or infection. Option A is incorrect as administering platelets typically does not require starting a new IV line unless indicated for the specific patient. Option C is not the priority as verifying the client's identity can be done at any point during the administration process but is not specific to the platelet transfusion itself. Option D, checking the client's chart for antibiotic use, is not directly related to ensuring the safety of the blood product container.
4. During an examination, the nurse notices that a female patient has a round “moon” face, central trunk obesity, and a cervical hump. Her skin is fragile with bruises. The nurse determines that the patient likely has which condition?
- A. Gigantism
- B. Acromegaly
- C. Cushing syndrome
- D. Marfan syndrome
Correct answer: Cushing syndrome
Rationale: Cushing syndrome is characterized by weight gain and edema with central trunk and cervical obesity (buffalo hump) and a round, plethoric face (moon face). Excessive catabolism in Cushing syndrome causes muscle wasting, weakness, thin arms and legs, reduced height, and thin, fragile skin with purple abdominal striae, bruising, and acne. Gigantism is characterized by increased height and weight and delayed sexual development, which are not present in the patient. Acromegaly results from excessive growth hormone secretion in adulthood, leading to bone overgrowth in specific areas like the face, head, hands, and feet. Marfan syndrome is an inherited connective tissue disorder characterized by a tall, thin stature and distinct features not seen in this patient. The combination of signs described in the question aligns with the clinical presentation of Cushing syndrome.
5. An examiner is using an ophthalmoscope to examine a patient’s eyes. The patient has astigmatism and is nearsighted. Which of these techniques by the examiner would indicate that the examination is being correctly performed?
- A. Rotating the lens selector dial to bring the object into focus
- B. Using the large full circle of light when assessing pupils that are not dilated
- C. Rotating the lens selector dial to the black numbers to compensate for astigmatism
- D. Using the grid on the lens aperture dial to visualize the external structures of the eye
Correct answer: Rotating the lens selector dial to bring the object into focus
Rationale: To correctly perform an eye examination using an ophthalmoscope on a patient with astigmatism and nearsightedness, the examiner should rotate the lens selector dial to bring the object into focus. This adjustment helps compensate for nearsightedness or farsightedness but does not correct astigmatism. Rotating the lens selector dial to the black numbers is not an appropriate technique for compensating for astigmatism. Using the grid on the lens aperture dial is primarily for visualizing external structures of the eye, not for addressing refractive errors. The large full circle of light is typically used when assessing dilated pupils, not for examining patients with astigmatism and nearsightedness. Therefore, the correct technique is rotating the lens selector dial to bring the object into focus.
