What drug should the nurse prepare for administration to reverse all signs of toxicity?
- A. Digibind (Digoxin)
- B. Atropine sulfate
- C. Naloxone (Narcan)
- D. Diazepam (Valium)
Correct Answer: C
Rationale: Naloxone, also known by the brand name Narcan, is used to reverse the effects of opioid overdose. Opioids can cause respiratory depression, sedation, and other signs of toxicity. Administering naloxone can quickly reverse these effects, restoring the patient's breathing and consciousness. This makes it the appropriate choice for reversing all signs of toxicity related to opioids. Digibind (Digoxin) is used to reverse toxicity from digoxin specifically. Atropine sulfate is used for bradycardia. Diazepam (Valium) is a benzodiazepine used for anxiety, seizures, and muscle relaxation, not for reversing toxicity.

A patient presents with urinary frequency, urgency, dysuria, and suprapubic pain. Urinalysis reveals pyuria and bacteriuria. Which of the following conditions is most likely?
- A. Acute glomerulonephritis
- B. Chronic kidney disease
- C. Urinary tract infection (UTI)
- D. Renal calculi
Correct Answer: C
Rationale: The patient's presentation of urinary frequency, urgency, dysuria, and suprapubic pain along with the urinalysis findings of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) are highly suggestive of a urinary tract infection (UTI). UTIs are one of the most common types of bacterial infections seen in clinical practice. The symptoms described are classic for a lower urinary tract infection. The presence of pyuria and bacteriuria on urinalysis further supports the diagnosis of a UTI. Acute glomerulonephritis typically presents with hematuria, proteinuria, hypertension, and edema. Chronic kidney disease is often asymptomatic in early stages and presents with symptoms like fatigue, edema, and changes in urination later on. Renal calculi are associated with severe colicky flank pain that can radiate to the groin, and they may present with
A patient presents with acute onset of severe headache, visual disturbances, and altered mental status. Imaging reveals a tumor compressing the optic chiasm. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Meningioma
- B. Glioblastoma multiforme
- C. Pituitary adenoma
- D. Medulloblastoma
Correct Answer: C
Rationale: Pituitary adenoma is the most likely neurological condition responsible for the described symptoms of acute onset severe headache, visual disturbances, and altered mental status when a tumor is found compressing the optic chiasm. Pituitary adenomas are benign tumors arising from the pituitary gland located at the base of the brain. As the tumor grows, it can compress nearby structures such as the optic chiasm, leading to visual disturbances (due to pressure on the optic nerves), severe headache (due to increased intracranial pressure), and altered mental status (due to effects on nearby brain structures).
A patient presents with fever, malaise, and a skin lesion resembling a "bull's eye" rash at the site of a tick bite. Which of the following is the most likely causative agent?
- A. Plasmodium falciparum
- B. Trypanosoma cruzi
- C. Borrelia burgdorferi
- D. Leishmania donovani
Correct Answer: C
Rationale: The most likely causative agent in this scenario is Borrelia burgdorferi, which is the bacterium responsible for causing Lyme disease. The classic presentation of Lyme disease includes fever, malaise, and a skin lesion resembling a "bull's eye" rash, known as erythema migrans. This rash typically appears at the site of a tick bite. If left untreated, Lyme disease can progress to involve multiple organ systems and lead to more severe complications. Plasmodium falciparum is the causative agent of malaria, which typically presents with symptoms such as fever, chills, and fatigue, but it does not cause a "bull's eye" rash. Trypanosoma cruzi is the parasite responsible for Chagas disease, which presents with symptoms such as fever, swelling at the site of entry (typically the bite wound), and enlarged lymph nodes, but it does not
Pulmonary Rehabilitation for COPD has a duration of at least 4 to 12 weeks. Which of the following should be avoided while patient is having this program?
- A. Pursed lip breathing
- B. Smoking cessation
- C. Aerobic, upper and lower body conditioning
- D. Peripheral muscle wasting
Correct Answer: B
Rationale: During pulmonary rehabilitation for COPD, smoking cessation should not be avoided but instead strongly encouraged. Smoking cessation is a crucial component in managing COPD and improving lung function. Continued smoking can exacerbate COPD symptoms and hinder the progress made through rehabilitation efforts. Therefore, it is essential for patients to quit smoking while undergoing pulmonary rehabilitation to maximize the benefits of the program and improve their overall lung health.
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.
