Nursing QUESTION #9302

In medical-surgical nursing, a patient on long-term corticosteroid therapy should be monitored for which of the following complications?

Hypoglycemia
Hyponatremia
Cushing's syndrome features including hyperglycemia, moon face, and osteoporosis✔️
Bradycardia

Correct Answer Logic:

Long-term corticosteroid therapy mimics endogenous excess cortisol, producing iatrogenic Cushing's Syndrome:

System	Effect of Excess Corticosteroids
Metabolic	Hyperglycemia (steroid-induced diabetes)
Appearance	Moon face, buffalo hump, central obesity, striae
Skeletal	Osteoporosis, vertebral fractures
Immune	Immunosuppression — increased infection risk (mask fever!)
Cardiovascular	Hypertension, fluid retention, edema
Electrolytes	Hypokalemia, hypernatremia
GI	Peptic ulcer formation

Critical nursing point: Patients on long-term steroids should never abruptly stop — risk of adrenal crisis (Addisonian crisis). Taper dosage gradually.

Question 8942

Economist Hlatshwayo found general uncertainty measures may not reflect specific policy uncertainty. For the UK, general economic policy uncertainty ____ using data from the graph.

aligned closely with tax/spending uncertainty in 2005 but differed greatly in 2009.
was substantially lower than tax/spending uncertainty each year from 2005-2010.
peaked in the same year that trade and tax/spending uncertainties were lowest.
was lower than trade uncertainty in 2005 and higher than trade uncertainty in 2010.✔️

Medicinal Chemistry and Biopharmaceutics QUESTION #3824

Question 8943

If $400$ mg of potassium permanganate is dissolved in $2.5$ L of water, what is the percentage concentration of the resulting solution?

$0.016\%$✔️
$0.032\%$
$0.064\%$
$0.16\%$

Correct Answer Logic:

$400\ \text{mg} = 0.4\ \text{g}$ in $2500\ \text{mL}$. Concentration $= \dfrac{0.4}{2500} \times 100 = 0.016\%\ \text{w/v}$.

Chemistry QUESTION #5539

Question 8944

A and B decompose by first-order kinetics with half-lives of 54.0 min and 18.0 min respectively. Starting from equimolar amounts of A and B, find the time (in min) at which $[A] = 16[B]$.

54
108✔️
162
216

Correct Answer Logic:

For equimolar start, $[A]_0 = [B]_0 = C$. $[A] = C\left(\frac{1}{2}\right)^{t/54}$, $[B] = C\left(\frac{1}{2}\right)^{t/18}$. Setting $[A]=16[B]$: $\left(\frac{1}{2}\right)^{t/54} = 16\left(\frac{1}{2}\right)^{t/18}$. $2^{-t/54} = 2^4 \cdot 2^{-t/18}$. $-\frac{t}{54} = 4 - \frac{t}{18}$. $\frac{t}{18}-\frac{t}{54} = 4 \Rightarrow \frac{3t-t}{54}=4 \Rightarrow \frac{2t}{54}=4 \Rightarrow t = 108\ \text{min}$.

Statistics QUESTION #2007

Question 8945

In the confidence interval for $p_1 - p_2$, with $\hat{p}_1 = 62/100 = 0.62$ and $\hat{p}_2 = 69/150 = 0.46$, the estimated standard error $SE(\hat{p}_1 - \hat{p}_2)$ equals:

$\sqrt{\dfrac{0.62(0.38)}{100} + \dfrac{0.46(0.54)}{150}}$✔️
$\sqrt{\dfrac{0.62(0.38) + 0.46(0.54)}{250}}$
$\dfrac{0.62 - 0.46}{\sqrt{250}}$
$\sqrt{\dfrac{0.54 \times 0.46}{250}}$

Correct Answer Logic:

For independent samples and a confidence interval (not a hypothesis test), the SE is $\sqrt{\dfrac{\hat{p}_1(1-\hat{p}_1)}{n_1} + \dfrac{\hat{p}_2(1-\hat{p}_2)}{n_2}} = \sqrt{\dfrac{0.62 \times 0.38}{100} + \dfrac{0.46 \times 0.54}{150}}$. The pooled estimate is used only for hypothesis testing, not CI construction.

The EXTERNAL DATA BUS (EDB) in a computer is best described as:

A type of USB cable used to connect external drives to the computer
A row of wires that interconnect the parts of the computer internally✔️
A software interface that manages communication between the operating system and hardware
The physical slot on the motherboard where expansion cards are inserted

Correct Answer Logic:

The External Data Bus (EDB) is a row of wires that interconnect the parts of our computer. It acts as the pathway through which data travels between the CPU, RAM, and other components. Think of it as the roads or highways through which data travels inside the computer.

Physics QUESTION #7055

Question 8952

A $192 \text{ g}$ unknown metal at $100^\circ\text{C}$ is dropped into a brass calorimeter ($128 \text{ g}$) containing $240 \text{ g}$ of water at $8.4^\circ\text{C}$. The final equilibrium temperature is $21.5^\circ\text{C}$. Calculate the specific heat of the metal (Specific heat of brass $= 394 \text{ J kg}^{-1}\text{K}^{-1}$, water $= 4184 \text{ J kg}^{-1}\text{K}^{-1}$).

$458 \text{ J kg}^{-1}\text{K}^{-1}$
$1232 \text{ J kg}^{-1}\text{K}^{-1}$
$916 \text{ J kg}^{-1}\text{K}^{-1}$✔️
$654 \text{ J kg}^{-1}\text{K}^{-1}$

Correct Answer Logic:

Using the Principle of Calorimetry: Heat lost by metal = Heat gained by (water + calorimeter).

$m_m s_m (100 - 21.5) = (m_w s_w + m_c s_c) (21.5 - 8.4)$

$0.192 \times s_m \times 78.5 = (0.24 \times 4184 + 0.128 \times 394) \times 13.1$

$15.072 s_m = (1004.16 + 50.432) \times 13.1 = 1054.592 \times 13.1 = 13815.15$

$s_m \approx 916.6 \text{ J kg}^{-1}\text{K}^{-1}$

Question 8954

Higher yield of NO in $\text{N}_2(\text{g})+\text{O}_2(\text{g})\rightleftharpoons 2\text{NO}(\text{g})$, $\Delta H=+180.7\ \text{kJ mol}^{-1}$:

B, C, D only
A, C, D only✔️
A, D only
B, C only

Correct Answer Logic:

Reaction is endothermic ($\Delta H>0$). By Le Chatelier's principle: (A) Higher temperature shifts equilibrium forward (endothermic) → higher NO yield ✓. (B) Lower temperature shifts backward → less NO ✗. (C) Higher [N$_2$] shifts equilibrium forward → more NO ✓. (D) Higher [O$_2$] shifts equilibrium forward → more NO ✓. Correct: A, C, D = option (2).

Disaster Management QUESTION #6556

Question 8960

What represents the most significant limitation of relying solely on structural measures for flood risk reduction?

High costs
Failure to address upstream catchment degradation, urban planning issues, and climate change, potentially creating false security✔️
Engineering complexity
Maintenance requirements

Correct Answer Logic:

Section 8 emphasizes combining structural measures with Eco-DRR, risk-sensitive planning, and climate adaptation. Structural measures alone don't address root causes (land use changes, ecosystem degradation, climate impacts) and can create moral hazard by encouraging development in protected but still at-risk areas.
