“The nurse checked the patient’s wristband, asked his name and date of birth, and compared them with the medicine order before giving the tablet.” Why did the nurse most likely do these checks?
“The nurse explained the new inhaler to Mr. Brown and then asked him to show her how he would use it.” Why did the nurse most likely ask him to demonstrate?
Work out 2 2/5 ÷ 5/9. Click the answer in lowest terms.
In a course, homework counts 20%, the midterm 40% and the final exam 40% of the grade. A student scores 66% on homework, 80% on the midterm and 68% on the final. What is the course grade G? Round to one decimal place.
Where does fertilisation most commonly take place?
During a lumbar puncture, which ligament is the last one pierced before the needle enters the epidural space?
What is the main function of pulmonary surfactant?
In primary adrenal insufficiency (Addison's disease), which combination is expected?
During which division of meiosis do homologous chromosomes separate?
A study finds that towns with more ice-cream sales also have more drownings. What is the best conclusion?
What is the molar mass of sulfuric acid, H₂SO₄ (H = 1, S = 32, O = 16 g/mol)?
Why does water have an unusually high boiling point for such a small molecule?
Choose the correct preposition: “The patient is allergic ___ penicillin.”
What is the indirect object in this sentence? “The nurse handed the patient a cup of water.”
Choose the meaning of the word in bold: “The nurse will palpate the abdomen.”
What does the term pericarditis mean?
Answer: C · To make sure the medicine went to the right patient
Checking the wristband, name and date of birth against the order confirms the patient’s identity, preventing medicine errors.
Answer: C · To check that he had understood correctly
Asking a patient to demonstrate (a “teach-back” or return demonstration) lets the nurse confirm that the patient can use the device correctly.
Answer: 4 8/25
Multiplying and dividing fractions: first turn mixed numbers into improper fractions (2 1/3 = 7/3). To multiply, multiply the numerators and the denominators. To divide, keep the first fraction, change ÷ to ×, and flip the second fraction (multiply by its reciprocal). Cancel common factors and write the result in lowest terms as a mixed number.
Answer: G = 72.4 %
Weighted average: when parts count for different percentages, multiply each score by its weight (as a decimal) and add. A plain mean of the scores is only right when every part counts equally.
Answer: B · Ampulla of the uterine tube
Fertilisation usually occurs in the ampulla of the uterine (fallopian) tube. The embryo then travels to the uterus to implant.
Answer: A · Ligamentum flavum
The needle passes skin, supraspinous and interspinous ligaments, then ligamentum flavum into the epidural space, then dura and arachnoid into the subarachnoid space.
Answer: A · To reduce surface tension in the alveoli
Surfactant, made by type II alveolar cells, lowers surface tension so alveoli do not collapse and the lungs are easier to inflate.
Answer: A · Low sodium, high potassium and high ACTH
Loss of aldosterone causes sodium loss and potassium retention. Low cortisol removes negative feedback, so ACTH rises and can cause skin pigmentation.
Answer: B · Meiosis I
In meiosis I homologous pairs separate, which halves the chromosome number. In meiosis II the sister chromatids separate, much as in mitosis.
Answer: D · They are correlated, perhaps because both rise in hot weather
Correlation does not prove causation. A hidden variable, warm weather, increases both ice-cream sales and swimming.
Answer: B · 98 g/mol
(2 × 1) + 32 + (4 × 16) = 2 + 32 + 64 = 98 g/mol.
Answer: B · Strong hydrogen bonds between its molecules must be broken
Boiling separates molecules from each other. Water's hydrogen bonds need more energy to overcome than the weak forces between similar-sized molecules such as methane.
Answer: D · to
The fixed expression is “allergic to” something, just as the noun is “an allergy to”.
Answer: A · patient
The direct object is what was handed (a cup). The indirect object receives the direct object: the patient.
Answer: C · Examine by touch
To palpate is to feel with the hands during a physical examination. Listening is auscultation.
Answer: B · Inflammation of the sac around the heart
Peri- (around) + cardi/o (heart) + -itis (inflammation): inflammation of the pericardium. Heart muscle inflammation is myocarditis.
