According to Johnson and Chang (2014), people living with chronic illness are more likely than the general population to:
- A. Have significantly reduced activity and subsequent loss of independence
- B. Be required to see their doctor more regularly
- C. Experience periods of hospitalisation as a consequence of acute flare-ups of their underlying chronic disease
- D. Stay home and reduce their activity and social interactions
Correct Answer: A
Rationale: Chronic illness curbs activity arthritis, COPD slash mobility, stealing independence, a standout hit over frequent doctor visits, hospital stays from flares, or self-imposed isolation. Those ripple too, but reduced function's the core burden, reshaping daily life. Nurses prioritize this, boosting support, a chronic truth where physical loss leads.

In caring for a patient with neutropenia, what tasks can be delegated to the nursing assistant?
- A. Take vital signs every 4 hours
- B. Report temperature elevation >100.4°F
- C. Assess for sore throat, cough, or burning with urination
- D. Gather the supplies to prepare the room for protective isolation
Correct Answer: A
Rationale: Neutropenia heightens infection risk, requiring team vigilance. Taking vital signs every 4 hours fits nursing assistants' scope routine monitoring flags fevers, key in neutropenia, without needing assessment skills. Reporting fever >100.4°F is their duty once detected, but assessing symptoms like sore throat or cough demands RN judgment to interpret infection signs. Gathering supplies for isolation is assistive, not evaluative, suiting their role. Handwashing's universal, not a task to delegate. Vital signs delegation ensures timely data collection, freeing nurses to analyze and act, a practical split in caring for this vulnerable patient.
The nursing instructor explains the difference between normal cells and benign tumor cells. What information does the instructor provide about these cells?
- A. Benign tumors grow through invasion of other tissue.
- B. Benign tumors have lost their cellular regulation from contact inhibition.
- C. Growing in the wrong place or time is typical of benign tumors.
- D. The loss of characteristics of the parent cells is called anaplasia.
Correct Answer: C
Rationale: Benign tumors are fundamentally different from malignant tumors in their behavior and characteristics. Unlike malignant tumors, which invade surrounding tissues, benign tumors do not grow through invasion but rather through hyperplasia, a controlled increase in cell number. They retain contact inhibition, a regulatory mechanism where normal cells stop dividing when they touch each other, preventing uncontrolled growth. The defining feature of benign tumors is that they consist of cells that are essentially normal but are growing in an inappropriate location or at an incorrect time, such as a lipoma in fatty tissue. Anaplasia, on the other hand, refers to the loss of differentiation and is a hallmark of malignant cancer cells, not benign ones. Thus, the instructor would emphasize that benign tumors are misplaced normal cells, making this the accurate statement. This distinction is critical for nursing students to understand, as it impacts diagnosis, treatment decisions, and patient education regarding the non-threatening nature of benign tumors compared to cancerous growths.
A female client is being treated for a deep-vein thrombus she developed post-operatively about one week ago and was treated with unfractionated heparin. Today she presents to the clinic with petechiae on bilateral hands and feet. Laboratory results show a platelet count of 42,000/mm³. The nurse is concerned about a drug reaction and anticipates the client has which of the following?
- A. Heparin-induced thrombocytopenia (HIT)
- B. Hemophilia A (classic hemophilia)
- C. Thrombotic thrombocytopenic purpura (TTP)
- D. Sickle cell crisis
Correct Answer: A
Rationale: Heparin can backfire petechiae and a platelet plunge to 42,000/mm³ post-DVT treatment scream HIT, an immune reaction trashing platelets, risking clots. Hemophilia's genetic, not drug-tied. TTP adds fever, neuro signs absent here. Sickle crisis pains, not bleeds like this. Nurses suspect HIT, anticipating heparin cessation and alternatives, a twist in this anticoagulation tale.
Which atypical pneumonia can be vaccinated against?
- A. coxiella burnetii
- B. mycoplasma pneumoniae
- C. chlamydia pneumoniae
- D. legionella
Correct Answer: A
Rationale: Coxiella Q fever has a vaccine, not mycoplasma, chlamydia duo, or legionella. Nurses jab this chronic farm bug shield.
Melatonin is a hormone that is involved in the regulation of the circadian rhythm. Features of melatonin include:
- A. It circulates in the cerebrospinal fluid and blood.
- B. It has a plasma elimination half-life of 4 h.
- C. It is derived from tryptophan.
- D. It activates the pituitary adenylate cyclase mechanism of circadian wakefulness.
Correct Answer: A
Rationale: Melatonin, produced by the pineal gland, regulates sleep-wake cycles. It circulates in blood and cerebrospinal fluid, crossing the blood-brain barrier to signal darkness via the suprachiasmatic nucleus (SCN). Its half-life is short, about 30-60 minutes, not 4 hours, enabling rapid response to light cues. Synthesized from tryptophan via serotonin, it's a biochemical derivative responsive to environmental triggers. It acts on melatonin receptors (MT1, MT2) in the SCN, suppressing wakefulness-promoting adenylate cyclase, not activating pituitary mechanisms for wakefulness that's a misattribution. Its role dampens alertness, promoting sleep. Circulation in bodily fluids ensures systemic distribution, aligning circadian rhythms with night, making it foundational to sleep physiology and fatigue management.
