1 | Loop Diuretics: Fluid & Electrolyte Complications
ANSWER TO KNOW: Fluid volume deficit + dysrhythmias
WHY: Furosemide is a loop diuretic that causes significant sodium, water, and potassium loss. Excessive diuresis can lead to
hypovolemia, while a falling potassium level increases the risk for cardiac dysrhythmias.
QUESTION HINT: Look for rapid weight loss + falling BP + increased urine output + hypokalemia after IV loop-diuretic therapy.
DON'T CONFUSE IT WITH: Expected diuresis in heart failure is beneficial. The danger appears when fluid loss becomes
excessive or potassium falls below normal.
2 | Alzheimer’s Disease: Home Orientation & Safety
ANSWER TO KNOW: Use a large-face clock for orientation.
WHY: Alzheimer’s disease causes progressive impairment in memory and orientation. Simple, highly visible environmental cues
such as a large clock can help the client remain oriented to time while supporting independence.
QUESTION HINT: Choose simple, familiar, nonrestrictive environmental cues that reduce confusion.
DON'T CONFUSE IT WITH: A dark environment can worsen disorientation and increase fall risk. Adequate lighting and
uncomplicated surroundings are safer.
3 | Prostate Brachytherapy: Radiation Safety
ANSWER TO KNOW: Use long-handled forceps to retrieve a dislodged radioactive implant.
WHY: Brachytherapy places a radioactive source close to or within the tumor. If an implant becomes dislodged, it should never
be handled directly. Long-handled forceps increase distance from the radiation source and reduce exposure.
QUESTION HINT: Internal radiation + dislodged implant = forceps + designated shielded container.
DON'T CONFUSE IT WITH: The nurse should not pick up the radioactive source with gloved hands. Radiation protection centers
on time, distance, and shielding.
4 | Stem Cell Transplant: Protective Environment
ANSWER TO KNOW: Positive-pressure airflow
WHY: Following a hematopoietic stem cell transplant, severe immunosuppression places the client at high risk for infection.
Positive-pressure airflow helps prevent contaminated hallway air from entering the client’s room, reducing exposure to airborne
microorganisms.
QUESTION HINT: When the goal is protecting an immunocompromised client from the environment, think positive pressure.
DON'T CONFUSE IT WITH: Negative pressure protects everyone outside the room from an infectious client, such as a client with
airborne tuberculosis.

5 | Spironolactone: Hyperkalemia
ANSWER TO KNOW: Muscle weakness + tingling/paresthesias
WHY: Spironolactone is a potassium-sparing diuretic. Excess potassium can interfere with neuromuscular and cardiac
conduction, producing weakness, paresthesias, and potentially life-threatening dysrhythmias.
QUESTION HINT: Spironolactone + muscle weakness/tingling + peaked T waves = think hyperkalemia.
DON'T CONFUSE IT WITH: Loop diuretics such as furosemide usually cause potassium loss, while spironolactone can cause
potassium retention.
6 | Opioid-Induced Respiratory Depression
ANSWER TO KNOW: Naloxone
WHY: Naloxone is an opioid antagonist that rapidly reverses opioid effects, including potentially fatal respiratory depression.
Respiratory status must continue to be monitored because naloxone can wear off before the opioid does.
QUESTION HINT: Opioid + decreased respirations/decreased LOC = naloxone.
DON'T CONFUSE IT WITH: Flumazenil reverses benzodiazepines. Naloxone reverses opioids.
7 | Osteomyelitis: Evidence of Ongoing Infection
ANSWER TO KNOW: Markedly elevated WBC count
WHY: Osteomyelitis is an infection of bone that often requires prolonged antimicrobial therapy. A significantly elevated WBC
count can indicate persistent or worsening infection and warrants further evaluation.
QUESTION HINT: Osteomyelitis + marked leukocytosis, fever, worsening pain, drainage, or inflammation = infection is not
adequately controlled.
DON'T CONFUSE IT WITH: Long-term IV antibiotic therapy can be expected with osteomyelitis. The duration of treatment alone
does not indicate deterioration.
8 | Seizure Precautions: Preventing Injury
ANSWER TO KNOW: Pad the upper side rails.
WHY: During a seizure, uncontrolled motor activity can cause the client to strike the bed rails and sustain an injury. Padded side
rails are an important seizure precaution for clients at risk.
QUESTION HINT: Seizure precautions = padded rails + oxygen + suction equipment available.
DON'T CONFUSE IT WITH: During an active seizure, do not restrain the client and do not place anything in the mouth. Protect the
head, maintain safety, and support the airway.
9 | Client Rights: Refusing Medication
ANSWER TO KNOW: Respect the refusal and notify the provider.
WHY: A competent client has the right to refuse treatment, including prescribed medications. The nurse should determine the
reason for refusal when appropriate, provide necessary education, respect the client’s decision, and communicate the refusal to
the provider.
QUESTION HINT: If a competent client says “I don’t want it,” think autonomy, not persuasion or coercion.
DON'T CONFUSE IT WITH: A prescription gives the nurse authorization to administer treatment. It does not eliminate the client’s
right to refuse it.
