Nursing Elites

1. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

• A. The patient is allergic to shellfish.
• B. The patient has a pacemaker.
• C. The patient suffers from claustrophobia.
• D. The patient takes antipsychotic medication.

Correct answer: B

Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.

2. A child is prescribed baclofen (Lioresal) via intrathecal pump to treat severe muscle spasms related to cerebral palsy. What teaching does the nurse provide the child and parents?

• A. Do not let this prescription run out.
• B. The medication may cause gingival hyperplasia.
• C. Periodic serum drug levels are needed.
• D. Watch for excessive facial hair growth.

Correct answer: A

Rationale: The correct teaching for the child and parents when a child is prescribed baclofen via an intrathecal pump is to not let the prescription run out. Abrupt discontinuation of intrathecal baclofen can lead to severe effects like high fever, altered mental status, and rebound spasticity and muscle rigidity. It is crucial for the parents to ensure there is always an adequate supply of this medication to prevent these adverse effects. Choices B and D are incorrect because gingival hyperplasia and hirsutism are side effects associated with phenytoin (Dilantin), not baclofen. Choice C is incorrect as serum drug levels are not typically monitored for intrathecal medications.

3. When obtaining a health history and physical assessment for a 36-year-old female patient with possible multiple sclerosis (MS), the nurse should

• A. assess for the presence of chest pain.
• B. inquire about urinary tract problems.
• C. inspect the skin for rashes or discoloration.
• D. ask the patient about any increase in libido.

Correct answer: B

Rationale: When assessing a patient for possible multiple sclerosis (MS), it is important to inquire about urinary tract problems as they are common symptoms of the condition, such as incontinence or retention. Chest pain is not typically associated with MS, so assessing for its presence is not a priority. Inspecting the skin for rashes or discoloration is not a typical manifestation of MS. Additionally, a decrease in libido, rather than an increase, is more commonly seen in patients with MS. Therefore, the most appropriate action for the nurse in this scenario is to inquire about urinary tract problems.

4. The nurse is counting a client's respiratory rate. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. Which respiratory rate should the nurse document?

• A. 14
• B. 16
• C. 17
• D. 28

Correct answer: B

Rationale: The most accurate respiratory rate is the second count obtained by the nurse, which was not interrupted by coughing. The nurse counted eight respirations over 30 seconds, so doubling this count gives a respiratory rate of 16 breaths per minute. This calculation is based on the assumption that the client's breathing pattern remained relatively stable during the two 30-second intervals. Options A, C, and D are incorrect because they do not reflect the accurate count obtained without interruptions. Choice B (16) is the correct answer as it reflects the uninterrupted count of respirations by the nurse.

5. When assessing the respiratory system of an older patient, which finding indicates that the nurse should take immediate action?

• A. Weak cough effort
• B. Barrel-shaped chest
• C. Dry mucous membranes
• D. Bilateral crackles at lung bases

Correct answer: D

Rationale: Bilateral crackles at lung bases indicate a potential acute issue like heart failure. Immediate action is necessary in this situation. The nurse should conduct further assessments such as oxygen saturation and inform the healthcare provider promptly. A barrel-shaped chest and hyperresonance to percussion are typical signs of aging and do not require immediate action. A weak cough effort is common in older patients due to age-related changes, and dry mucous membranes are also expected in older individuals. While these findings may warrant further evaluation, they do not demand immediate action like bilateral crackles at lung bases.
