A nurse is preparing to assist with a peripherally inserted central catheter (PICC) insertion for a patient. What action should the nurse prioritize to maintain procedural asepsis?
- A. Wearing sterile gloves and a surgical mask during the procedure
- B. Cleansing the insertion site with alcohol-based antiseptic solution
- C. Using a sterile drape to cover the patient during the procedure
- D. Avoiding unnecessary movement or talking during the procedure
Correct Answer: B
Rationale: The nurse should prioritize cleansing the insertion site with an alcohol-based antiseptic solution to maintain procedural asepsis during a peripherally inserted central catheter (PICC) insertion. Proper skin preparation is essential in reducing the risk of introducing pathogens into the patient's bloodstream during the insertion process. Alcohol-based antiseptic solutions are effective in reducing the number of microorganisms on the skin surface. Wearing sterile gloves and following other sterile techniques are also crucial, but preparing the insertion site with the antiseptic solution is the initial step in maintaining asepsis during the procedure.

The best prevention management of contact latex allergy is ______.
- A. applying lotion before gloving
- B. avoidance of latex products
- C. avoiding rubberized goods
- D. resigning from the job
Correct Answer: B
Rationale: The best prevention management of contact latex allergy is to avoid latex products entirely. Latex allergies can range from mild skin irritation to severe reactions such as anaphylaxis. This means that even applying lotion before using latex gloves may not be sufficient to prevent an allergic reaction in individuals who are sensitized to latex. It is important for individuals with latex allergy to completely avoid exposure to latex products, including rubberized goods, to prevent triggering an allergic response. Resigning from the job is not a practical solution and should not be necessary if proper precautions are taken to avoid latex exposure.
A patient presents with redness, pain, and photophobia in the left eye. Slit-lamp examination reveals ciliary injection, corneal edema, and a mid-dilated pupil with fixed reaction to light. Which of the following conditions is most likely responsible for this presentation?
- A. Anterior uveitis
- B. Acute angle-closure glaucoma
- C. Endophthalmitis
- D. Corneal abrasion
Correct Answer: A
Rationale: The presentation described is consistent with anterior uveitis. Anterior uveitis involves inflammation of the iris and ciliary body. Patients typically present with symptoms such as redness, pain, photophobia, and blurred vision. The slit-lamp examination findings of ciliary injection (redness and dilation of blood vessels in the iris and ciliary body), corneal edema, and a mid-dilated pupil with a fixed reaction to light (due to ciliary muscle spasm causing decreased accommodation) are characteristic of anterior uveitis. This condition is often idiopathic but can be associated with various systemic diseases like ankylosing spondylitis, inflammatory bowel disease, and other autoimmune disorders. Treatment involves addressing the inflammation with topical corticosteroids and, in some cases, cycloplegic agents to reduce pain and inflammation.
A patient presents with recurrent episodes of sudden, severe vertigo lasting hours, accompanied by nausea, vomiting, and nystagmus. Vestibular function tests demonstrate unilateral weakness. Which of the following conditions is most likely responsible for this presentation?
- A. Vestibular neuritis
- B. Benign paroxysmal positional vertigo (BPPV)
- C. Ménière's disease
- D. Acoustic neuroma Ophthalmology
Correct Answer: A
Rationale: The patient's presentation of recurrent episodes of sudden, severe vertigo lasting hours with nausea, vomiting, and nystagmus, along with unilateral weakness on vestibular function tests, is most consistent with vestibular neuritis. Vestibular neuritis is characterized by inflammation of the vestibular nerve leading to sudden onset vertigo that can last for hours to days. It is often associated with nausea, vomiting, and nystagmus. Unilateral weakness on vestibular function tests indicates dysfunction of one vestibular system. Differential diagnosis for this type of presentation includes other conditions such as Meniere's disease, BPPV, and acoustic neuroma. However, the combination of symptoms and unilateral vestibular weakness makes vestibular neuritis the most likely diagnosis in this case.
A pregnant woman presents with sudden onset of severe abdominal pain and vaginal bleeding. On examination, her abdomen is rigid, and fetal parts are palpable abdominally. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Pelvic inflammatory disease
- C. Uterine rupture
- D. Ovarian torsion
Correct Answer: C
Rationale: Uterine rupture is the most likely cause of these symptoms in a pregnant woman presenting with sudden onset of severe abdominal pain, vaginal bleeding, rigidity of the abdomen, and palpable fetal parts abdominally. Uterine rupture is a rare but serious complication of pregnancy, typically occurring during labor in women with a previous cesarean delivery or other uterine scars. The sudden onset of severe abdominal pain can be associated with vaginal bleeding due to the tearing of the uterine wall, causing fetal parts to be palpable abdominally. This is a life-threatening emergency that requires immediate medical intervention. Ectopic pregnancy, pelvic inflammatory disease, and ovarian torsion may present with abdominal pain and vaginal bleeding but would not typically present with palpable fetal parts abdominally in a pregnant woman.
Which is the MOST important criterion in budgeting?
- A. Flexibility
- B. Consistency
- C. Standardized
- D. Cost of effectiveness
Correct Answer: A
Rationale: Flexibility is the most important criterion in budgeting because it allows for adjustments to be made as circumstances change. Budgeting is a dynamic process, and having a flexible budget enables organizations or individuals to adapt to unexpected changes in income or expenses. This helps in ensuring that resources are allocated efficiently and effectively to meet the overall financial goals. Consistency, standardization, and cost-effectiveness are also important considerations in budgeting, but flexibility is key to successfully managing financial resources in a changing environment.
