A patient presents with acute onset of severe vertigo, nausea, vomiting, and nystagmus. Symptoms are worsened with head movement. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Ménière's disease
- B. Vestibular neuritis
- C. Benign paroxysmal positional vertigo (BPPV)
- D. Labyrinthitis
Correct Answer: B
Rationale: Vestibular neuritis is a condition characterized by the acute onset of severe vertigo, nausea, vomiting, and nystagmus. These symptoms are typically worsened by head movement. Vestibular neuritis is caused by inflammation of the vestibular nerve, which plays a key role in balance and spatial orientation. The classic presentation of these symptoms, along with the absence of hearing loss (which is seen in labyrinthitis), points towards vestibular neuritis as the most likely cause in this scenario. Meniere's disease presents with recurrent episodes of vertigo, hearing loss, tinnitus, and sensation of fullness in the ear. Benign paroxysmal positional vertigo (BPPV) is characterized by brief episodes of vertigo triggered by changes in head position.

A patient with a history of heart failure is prescribed a beta-blocker. Which assessment finding indicates a therapeutic effect of beta-blocker therapy?
- A. Decreased heart rate
- B. Increased blood pressure
- C. Elevated respiratory rate
- D. Worsening dyspnea Pharmacology
Correct Answer: A
Rationale: Beta-blockers are medications commonly used in the management of heart failure. One of the therapeutic effects of beta-blockers is to decrease the heart rate. By blocking the action of adrenaline on the heart, beta-blockers help to slow down the heart rate, reduce the workload on the heart, and improve overall heart function. In patients with heart failure, a decreased heart rate is a favorable outcome as it can help improve cardiac output and reduce symptoms of heart failure such as fatigue and shortness of breath. Monitoring the heart rate is an important assessment parameter to evaluate the effectiveness of beta-blocker therapy in patients with heart failure. Therefore, a decreased heart rate would indicate a therapeutic effect of beta-blocker therapy in this patient.

A pregnant woman presents with recurrent episodes of severe abdominal pain, bloating, and constipation. On examination, an abdominal mass is palpable, and bowel sounds are diminished. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Threatened abortion
- C. Placenta previa
- D. Ovarian torsion
Correct Answer: D
Rationale: Ovarian torsion is the most likely cause of the pregnant woman's symptoms as described. Ovarian torsion occurs when the ovary twists on its pedicle, leading to compromised blood flow to the ovary. This can cause severe abdominal pain, bloating, and constipation. On examination, an abdominal mass may be palpable due to an enlarged, twisted ovary. Bowel sounds may be diminished due to the effect of the torsion on surrounding structures. Ectopic pregnancy, threatened abortion, and placenta previa are less likely to present with an abdominal mass and diminished bowel sounds.
Nurse Roberto is aware that a client who has experienced cardiac arrest is MOST at risk for which of the following imbalances?
- A. Metabolic alkalosis
- B. Metabolic acidosis
- C. Respiratory alkalosis
- D. Respiratory acidosis
Correct Answer: D
Rationale: When a client experiences cardiac arrest, their breathing may become insufficient, leading to inadequate elimination of carbon dioxide (CO2) from the body. With reduced CO2 elimination, the level of CO2 in the bloodstream increases, causing respiratory acidosis. This imbalance is characterized by a decrease in blood pH along with an increase in CO2 levels in the blood, resulting in an acidic environment. Respiratory acidosis is the most common imbalance seen in clients who have experienced cardiac arrest, as impaired gas exchange impacts the body's ability to maintain proper acid-base balance.
A nurse is preparing to perform an intramuscular (IM) injection for a patient. What action should the nurse take to ensure proper injection technique?
- A. Selecting a small-gauge needle to minimize patient discomfort
- B. Administering the injection rapidly to reduce patient anxiety
- C. Aspirating the syringe to confirm needle placement before injection
- D. Inserting the needle at a 90-degree angle into the muscle
Correct Answer: D
Rationale: When performing an intramuscular (IM) injection, the nurse should insert the needle at a 90-degree angle into the muscle. This angle helps ensure proper and deep penetration into the muscle tissue for effective administration of the medication. It also helps prevent leakage or tissue damage at the injection site. Additionally, inserting the needle at a 90-degree angle facilitates accurate delivery of the medication into the muscle where it can be absorbed properly. Therefore, selecting the correct angle for inserting the needle is critical in ensuring the success and effectiveness of the IM injection.
