1. An adult who was recently diagnosed with glaucoma tells the nurse, 'it feels like I am driving through a tunnel.' The client expresses great concern about going blind. Which nursing instruction is most important for the nurse to provide this client?
- A. Maintain prescribed eye drop regimen
- B. Avoid frequent eye pressure measurements
- C. Wear prescription glasses
- D. Eat a diet high in carotene
Correct answer: A
Rationale: The correct answer is A: Maintain prescribed eye drop regimen. In glaucoma, maintaining the prescribed eye drop regimen is crucial for controlling intraocular pressure, which helps in preventing vision loss. Consistent use of eye drops as directed can slow down the progression of the disease and preserve vision. Choice B is incorrect because avoiding frequent eye pressure measurements does not address the primary treatment for glaucoma. Choice C is incorrect as wearing prescription glasses may be helpful for vision correction but does not directly address the management of glaucoma. Choice D is incorrect because while a diet high in carotene may promote overall eye health, it is not the most important instruction for managing glaucoma.
2. After delegating care to an unlicensed assistive personnel (UAP) for a client who is prescribed habit training to manage incontinence, a nurse evaluates the UAP’s understanding. Which action indicates the UAP needs additional teaching?
- A. Toileting the client after breakfast
- B. Changing the client’s incontinence brief when wet
- C. Encouraging the client to drink fluids
- D. Recording the client’s incontinence episodes
Correct answer: B
Rationale: The correct action that indicates the UAP needs additional teaching is choice B, 'Changing the client’s incontinence brief when wet.' Habit training is a technique used to manage incontinence, and it is undermined by the use of absorbent incontinence briefs or pads. The nurse should re-educate the UAP on the technique of habit training, which involves scheduled toileting and promoting bladder control. Choices A, C, and D are appropriate actions that support the client’s care: toileting the client after meals, encouraging fluid intake, and documenting incontinence episodes are all important aspects of managing incontinence and monitoring the client's condition.
3. Which of the following is a key symptom of hypothyroidism?
- A. Weight loss.
- B. Heat intolerance.
- C. Cold intolerance.
- D. Increased appetite.
Correct answer: C
Rationale: Cold intolerance is a key symptom of hypothyroidism because a decreased metabolic rate leads to a reduced ability to regulate body temperature. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism, where excess thyroid hormone leads to an increased sensitivity to heat. Increased appetite (Choice D) is not typically seen in hypothyroidism; instead, individuals with hypothyroidism may experience weight gain due to the slowed metabolism.
4. A patient is diagnosed with Mycoplasma pneumonia. Which antibiotic will the nurse expect the provider to order to treat this infection?
- A. Azithromycin (Zithromax)
- B. Clarithromycin (Biaxin)
- C. Erythromycin (E-Mycin)
- D. Fidaxomicin (Dificid)
Correct answer: C
Rationale: Erythromycin is the drug of choice for treating Mycoplasma pneumonia. Mycoplasma pneumonia is typically sensitive to macrolide antibiotics, with erythromycin being one of the first-line agents. Azithromycin and clarithromycin are also effective in treating Mycoplasma pneumonia, but erythromycin is specifically mentioned as the drug of choice in this context. Fidaxomicin, on the other hand, is not indicated for the treatment of Mycoplasma pneumonia and is primarily used to treat Clostridium difficile infections.
5. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?
- A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
- B. A serum drug level greater than the MEC broadens the spectrum of the drug.
- C. A serum drug level greater than the MEC helps eradicate bacterial infections.
- D. A serum drug level greater than the MEC increases the therapeutic index.
Correct answer: C
Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.
