Use the drip-rate formula:

(\text{gtt/min}=\dfrac{\text{Volume (mL)}\times \text{Drop factor (gtt/mL)}}{\text{Time (min)}}).

Convert hours to minutes: (5\ \text{hr} = 300\ \text{min}). Compute:

(\dfrac{750 \times 20}{300}=\dfrac{15{,}000}{300}=50\ \text{gtt/min}).

Thus, C is correct. Check distractors: A (40) would result from dividing by 375 minutes (too long) or using a 16 gtt/mL set erroneously. B (45) might come from rounding after an incorrect intermediate. D (60) equates to 1 gtt/sec and would correspond to 900 mL in 5 hr at this drop factor—too fast. On TEAS IV math, carry units throughout to avoid mixing mL/hr with gtt/min. A useful mental shortcut is to simplify first: (750/300 = 2.5\ \text{mL/min}); then multiply by the drop factor: (2.5 \times 20 = 50\ \text{gtt/min}). Always ensure time is in minutes when the answer requires per minute, and use the specified drop factor (10, 15, 20, or 60 are common).

The parasympathetic division (“rest and digest”) promotes energy conservation and digestive activity: it slows heart rate (vagal effect on SA node), constricts pupils (miosis), bronchoconstricts airways modestly, and increases GI motility and secretions through muscarinic (M₃) receptors, facilitating digestion and absorption. Therefore B is correct. A, C, and D describe sympathetic (“fight or flight”) responses: A lists tachycardia and bronchodilation with decreased GI activity; C covers metabolic mobilization (glycogenolysis, lipolysis) mediated by catecholamines; D includes mydriasis (pupil dilation) and reduced salivation—both sympathetic. TEAS A&P often asks you to map autonomic outputs to organs: Sympathetic via norepinephrine/epinephrine acts on α/β receptors to increase cardiac output, dilate bronchi (β₂), shunt blood to muscle, and mobilize fuels, while parasympathetic via acetylcholine on muscarinic receptors supports digestion, elimination, and glandular secretions. Clinically, anticholinergic drugs (e.g., atropine) block parasympathetic tone and cause dry mouth, tachycardia, decreased bowel sounds, and mydriasis; cholinergic agonists or acetylcholinesterase inhibitors produce the opposite. Distinguishing these patterns helps interpret vital-sign changes and medication effects.

In formal scientific style (as on TEAS), data is treated as a plural noun taking plural verbs and pronouns: “data are.” Option B correctly uses plural these data are and maintains agreement in the independent clause (“the team will repeat”). Option A treats data as singular—common in informal usage but not preferred on exams. C mismatches demonstrative and verb (“This data are”) and also drops agreement in the second clause (“team repeat”). D pairs a plural subject with a singular verb (“data was”) and adds a comma error (missing comma after “therefore” when used as a conjunctive adverb within one sentence or, alternatively, should use a semicolon then comma: “; therefore,”). TEAS grammar items reward careful subject–verb agreement with collective and Latin-derived plurals: bacteria are, criteria are, media are (though “the media is” is creeping into modern usage). When unsure, substitute a clearly plural noun—“the results are”—to test agreement. Maintaining consistent formal style is crucial in professional documentation and research reporting.

Upon antigen exposure, B lymphocytes with matching receptors are activated (often with helper T-cell costimulation via cytokines like IL-4/IL-5). Activated B cells differentiate into plasma cells, specialized effectors that secrete antibodies (immunoglobulins IgM, IgG, IgA, IgE, IgD) targeted to the antigen. These antibodies neutralize toxins/viruses, opsonize pathogens to enhance phagocytosis, and activate complement, facilitating clearance. Some activated B cells become memory B cells, enabling a faster, stronger secondary response upon re-exposure—the immunologic basis of vaccination. Helper T cells (A) do not secrete antibodies; they coordinate the response by releasing cytokines that activate B cells and macrophages and assist cytotoxic T cells. Cytotoxic T cells (C) kill infected or malignant cells directly via perforin/granzyme pathways; they are part of cell-mediated immunity. Macrophages (D) are innate immune phagocytes and antigen-presenting cells; they ingest pathogens and present antigen to T cells but do not produce immunoglobulins. TEAS Science often contrasts humoral immunity (B cells/antibodies) with cell-mediated immunity (T cells). Remember the flow: antigen recognition → clonal selection → plasma cells (antibody factories) and memory cells → enhanced secondary response.

Use fewer with countable nouns and less with uncountable (mass) nouns. Option B pairs the forms correctly: fewer open slots (slots are countable items) and less time (time is a mass concept). Option A should read “fewer patients” because patients are discrete, countable individuals. In C, equipment is a mass noun; the correct phrasing is “less equipment was available.” Option D is tricky: when a specific count is referenced (“ten people”), formal usage prefers fewer, as in “fewer than ten people,” though “less than ten” appears in casual speech. TEAS favors prescriptive grammar for clarity in professional writing. A quick test is to try a number: if you can say “many” or add an “-s” (many slots, many patients), use fewer; if you pair with “much” (much time, much equipment), use less. Proper word choice enhances precision in clinical documentation and policies (e.g., “fewer falls,” “less bleeding”) and prevents ambiguity when quantifying outcomes or resources.
